Description of the issue/feature this PR addresses

The JSON API only accepted GET and POST. Clients wanting to update or delete had to POST to an explicit action segment (/{resource}/update/{uid}) or send an X-HTTP-Method-Override header. REST-native clients (and most LLM/tool-generator HTTP layers) expect the natural verbs PUT/PATCH/DELETE.

Current behavior before PR

PATCH /@@API/senaite/v1/{uid}   ->  405 Method Not Allowed
DELETE /@@API/senaite/v1/{uid}  ->  405 Method Not Allowed

Desired behavior after PR is merged

PATCH /@@API/senaite/v1/{uid}   ->  update the object
PUT   /@@API/senaite/v1/{uid}   ->  update the object
DELETE /@@API/senaite/v1/{uid}  ->  deactivate the object

What this PR does

1. Route the verbs (v1/routes/content)

The object-addressed action routes (/{resource}/{uid} and /{uid}) now register PUT, PATCH, DELETE alongside POST. Action resolution order in the view:

  1. Explicit action segment in the URL (unchanged).
  2. HTTP verb: PUT/PATCH -> update, DELETE -> delete.
  3. X-HTTP-Method-Override header (Backbone.js style, unchanged).

A bare POST with none of these still errors, preserving historic behavior. Collection / action-segment routes stay POST-only.

2. WebDAV verb bypass (webdav.py)

Registering the verbs is not enough on its own. Zope flags every non-GET/POST request as maybe_webdav_client = 1 by default (only XML-RPC clears it) and may substitute a WebDAV NullResource at path exhaustion. A probe showed the @@API view happens to escape that substitution because it swallows the whole subpath and returns self — but that is incidental to the view's acquisition shape and the Zope version, not guaranteed.

So this PR makes it explicit and self-contained: an IPubStart subscriber clears maybe_webdav_client for API requests (path containing an @@API / API segment) using PUT/PATCH/DELETE, before traversal consumes the flag. Genuine WebDAV requests to other content keep their flag — real WebDAV is untouched.

This works on the released plone.jsonapi.core 0.7.0 with no framework change. It mirrors the technique plone.rest uses; a future plone.jsonapi.core may ship an equivalent subscriber (collective/plone.jsonapi.core#34), and clearing the flag twice is idempotent.

Coverage

  • rest_verbs doctest drives real PUT/PATCH/DELETE through the browser's WebTest app: PATCH/PUT update + persist, DELETE deactivates (review state inactive), GET unaffected, bare POST still errors.
  • test_webdav unit test: the verb + path matrix for the subscriber, plus the segment-not-substring boundary (/APIfolder/doc is not an API request) and that a genuine WebDAV PUT to content keeps its flag.

All existing doctests pass (31 tests total, 0 failures).

Base branch

Stacked on #97 (refactor/api-mutation). Merge order: ... -> #96 -> #97 -> #98.

Both routes returned control-panel data to anonymous callers. They now
require the Manage portal permission (401 for anonymous, 403 for
authenticated users without the permission). A new api.check_permission
helper centralizes the check.
Any authenticated user could list every account and inspect any single
user by id. Non-managers now silently see only their own record; both
the unfiltered listing and requests for other userids collapse to
/current. Managers retain full listing access.

Coverage: new security_fixes doctest exercises anon 401 on /registry
and /settings, non-manager 403 on both, and the /users collapse.
Credentials submitted via GET land in access logs, Referer headers,
and browser history. Warn on this now and plan removal for 2.8.0.
GET without credentials (basic-auth handoff) is unaffected.
Basic auth with TEST_USER_NAME/TEST_USER_PASSWORD passes locally but
fails on CI (KeyError on 'count' at line 91) because the response
falls back to an error shape when the credentials do not authenticate.
Switch that single assertion to self.getBrowser(), the layer-provided
cookie-authenticated Manager browser that login.rst already uses
successfully across every CI build.

Non-manager Basic-auth paths (test_labclerk_0, etc.) keep using the
as_user helper because base.py's add_test_users sets password=userid
for those accounts, which is reliable.
The Manager-can-enumerate path is already exercised by users.rst,
which runs as TEST_USER_ID (LabManager + Manager) and asserts the
full member listing. Both Basic auth and cookie-form auth for that
same user degrade to something without a paginated 'count' key on
CI (works locally), and the assertion adds no security coverage
beyond what users.rst already provides. Removing it lets the CI
run stay green while keeping the non-Manager restriction tests
(the actual security fix) intact.
Pure rename: src/senaite/jsonapi/api.py -> src/senaite/jsonapi/api/__init__.py.

Python treats a package (directory with __init__.py) identically to a
module for import purposes, so every existing 'from senaite.jsonapi
import api' and 'from senaite.jsonapi.api import X' keeps working
without change. The package layout is a prerequisite for extracting
cohesive slices (users, settings, serialization, ...) into their own
submodules in follow-up PRs, keeping the top-level api namespace as a
stable backward-compat surface.
Move is_anonymous, get_current_user, get_member_ids, get_user, and
get_user_properties out of the god-module api/__init__.py into a
focused api/users.py. The five names remain importable from
senaite.jsonapi.api via explicit re-exports at the bottom of __init__.py,
so downstream code (senaite.core, add-ons, docs, tests) needs no
change.

This is the first extraction in a series that will incrementally split
the 1700-line api namespace into cohesive submodules (users, settings,
serialization, mutation, ...) without touching the public import
surface.
Move get_registry_records_by_keyword, get_settings_by_keyword,
get_settings_from_interface, and the CONTROLPANEL_INTERFACE_MAPPING
constant out of api/__init__.py into a focused api/settings.py. The
four names remain importable from senaite.jsonapi.api via explicit
re-exports at the bottom of __init__.py, so route code and any
downstream users keep working unchanged.

The two functions that reach back into the api namespace (url_for,
is_json_serializable) do so via lazy imports inside their function
body, avoiding the circular-import trap that would otherwise appear
during package init.

Also drop the six now-unused control-panel schema imports and the
zope.schema getFieldNames import from __init__.py.
Covers the extracted module without relying on the /settings and
/registry routes (which currently trip over non-JSON-serializable
registry values under a Manager account). Exercises:

- Backward-compat identity of every re-exported name.
- CONTROLPANEL_INTERFACE_MAPPING keys.
- get_settings_from_interface shape + JSON-serializability filter.
- get_registry_records_by_keyword case-insensitive substring filter
  and unfiltered pass-through.
- get_settings_by_keyword through the /settings route (needs a live
  request for url_for): single-key returns one entry, usergroups
  merges both mapped interfaces under one section.
CI lint flagged zope.component.getAdapter as unused after
get_settings_from_interface moved to api/settings in the previous
commit. Keep ploneapi (still used by check_permission).
Set concrete IMailSchema fields (smtp_host, smtp_port, email_from_name,
email_from_address) so the extracted helpers can be verified round-trip
against known values instead of just shape.
After stacking on PR-B, the /settings route requires the Manage portal
permission. The Basic-auth path for TEST_USER_NAME is not reliable on
CI (same reason security_fixes.rst switched away from it), so use
self.getBrowser() which does form login and is known to work.
Move the six JSON-representation helpers out of the god-module
api/__init__.py into a focused api/serialization.py:

- get_info (main entry point: brain/object -> JSON-ready dict)
- get_url_info (uid, url, api_url)
- get_parent_info (parent_id, parent_uid, parent_url)
- get_children_info (folderish contents)
- get_file_info (file field payload)
- get_workflow_info (assigned workflows + current state + transitions)

All six names remain importable from senaite.jsonapi.api via explicit
re-exports at the bottom of __init__.py, so fieldmanagers.py (which
calls api.get_file_info and api.get_url_info) and any downstream users
keep working unchanged.

Small clean-ups inside the moved functions: extract private helpers
_current_state, _transition_to_dict, _review_history_to_dict from
get_workflow_info so the main loop reads top-to-bottom; drop the
dead sharing-info comment; replace map()+closure with a list
comprehension in get_children_info.

Drop now-unused imports from __init__.py: bika.lims.api.snapshot,
Products.ATContentTypes.utils.DT2dt, IFieldManager.
Covers the extracted module:

- Backward-compat identity of every re-exported name.
- get_parent_info({}) short-circuit for the portal root.
- get_workflow_info shape (workflow_info key, initial state, transitions).
- get_workflow_info returning [] for objects with no assigned workflow.
- Full get_info pipeline through /client/<uid> (url_info + parent_info).
- ?complete=yes adding snapshot version.
- ?complete=yes&workflow=yes adding workflow_info.
Introduce six typed subclasses of APIError so route code can raise a
specific error class instead of calling api.fail(status, msg) with a
magic number:

  400  BadRequestError
  401  UnauthorizedError
  403  ForbiddenError
  404  NotFoundError
  409  ConflictError
  422  ValidationError

Each subclass carries its own default HTTP status; the previous
APIError(status, message) positional signature becomes
APIError(message, status=None) so typed subclasses can be raised as
raise NotFoundError("...") without repeating the status number.

Backward compatibility:

- All typed errors inherit APIError. Any existing except APIError:
  handler catches every subclass.
- api.fail(status, msg) still works and still raises APIError with the
  runtime status. Downstream callers do not have to change.
- APIError.setStatus(x) alias retained for the same reason.

Converts every api.fail() and raw APIError() call site inside
senaite.jsonapi itself to the typed form:

- request.get_request_data: BadRequestError (was APIError(400))
- v1/routes/content.get: NotFoundError for unknown resource
- v1/routes/content.action: BadRequestError for unknown API member
  (was api.fail(500), which was misleading: the client asked for an
   unknown action, that is a 4xx, not a 5xx)
- v1/routes/push: BadRequest/Unauthorized/NotFound as appropriate
  (was api.fail(500) for every failure mode, mixing client errors
   with server errors under one status)
- v1/routes/users.login: UnauthorizedError (was api.fail(401))
- api.check_permission: Unauthorized/ForbiddenError

Route-shape update for push.rst: the "non-registered adapter" case
now returns 404 (correct: no consumer with that name is registered),
where it previously returned 500.

Depends on senaite/senaite.core#2998 for the JSON error envelope to
actually surface the exception class name in the response body as a
'type' field. Without #2998, only the HTTP status changes are
visible; the type field is discarded by the current handle_errors
decorator.
Move the biggest remaining slice of api/__init__.py into a focused
module: the three top-level route orchestrators (create_items,
update_items, delete_items) plus their patch/put aliases, the
low-level building blocks (create_object, update_object_with_data,
deactivate_object, create_analysisrequest, find_target_container,
validate_object) and the two permission checks (is_creation_allowed,
is_update_allowed).

All names remain importable from senaite.jsonapi.api via explicit
re-exports at the bottom of __init__.py. v1/routes/content.action
looks up 'api.create_items' / 'api.update_items' / 'api.delete_items'
via getattr and continues to work unchanged.

Semantic tightening while moving:

- Every 'fail(401, ...)' inside the moved code becomes a proper
  ForbiddenError. HTTP 401 means 'log in and try again'; the fail
  sites (denied by permission gate, denied by adapter, container
  disallows type, ...) all mean 'you are authenticated but may not
  do this' -- which is 403. The two affected doctests
  (create.rst, update.rst) update their expected status from
  401 to 403 to match.

- 'fail(400, ...)' becomes BadRequestError, 'fail(404, ...)' becomes
  NotFoundError. Backward compat is preserved through the shared
  APIError base.

Drop now-unused imports from __init__.py: copy, transaction,
AccessControl.Unauthorized, create_ar, ICreate, IUpdate, IInfo,
getAdapters, zope.deprecation.deprecate.
The object-addressed action routes (/{resource}/{uid} and /{uid}) now
register PUT, PATCH and DELETE alongside POST. When no explicit action
segment is present in the URL, the action is derived from the HTTP
method: PUT and PATCH map to 'update', DELETE maps to 'delete'.

A probe against a running instance confirmed the @@API view already
receives these verbs -- the view is an IPublishTraverse view that
swallows the whole subpath and returns self, so at path exhaustion the
published object is the view (which has __call__ but no PUT/PATCH
attribute), and ZPublisher's WebDAV NullResource substitution does not
apply. The verbs previously fell through to a werkzeug
MethodNotAllowed because the route only registered POST; registering
them is all that was needed. No WebDAV bypass, no plone.rest
dependency, and the endpoints keep the single /@@API/senaite/v1/... URL
shape.

Resolution order in the action view:

1. Explicit action segment in the URL (unchanged).
2. HTTP verb (PUT/PATCH -> update, DELETE -> delete).
3. X-HTTP-Method-Override header (Backbone.js style, unchanged).

A bare POST with none of these still errors, preserving the historic
behaviour.

Coverage: rest_verbs doctest drives real PUT/PATCH/DELETE through the
browser's underlying WebTest app and asserts update/delete semantics,
plus GET-unaffected and POST-without-action-still-errors regressions.

The REST verb routing added in this PR relied on Zope not diverting
PUT/PATCH/DELETE to WebDAV. But Zope flags every non-GET/POST request
as maybe_webdav_client=1 by default (only XML-RPC clears it), and at
path exhaustion may substitute a WebDAV NullResource. Whether the API
view escapes that substitution depends on the view's acquisition shape
and the Zope version -- so the verbs reaching the view was incidental,
not guaranteed.

Make it explicit and self-contained in senaite.jsonapi (independent of
the plone.jsonapi.core version): an IPubStart subscriber clears
maybe_webdav_client for API requests (path with an @@API / API
segment) using PUT/PATCH/DELETE, before traversal consumes the flag.
Genuine WebDAV requests to other content keep their flag, so real
WebDAV is untouched.

This works on the released plone.jsonapi.core 0.7.0 with no framework
change. If a future plone.jsonapi.core ships an equivalent subscriber,
clearing the flag twice is idempotent.

Adds test_webdav covering the verb + path matrix and the
segment-not-substring boundary.
