Sync projects on repository push via webhooks

[fernandorocagonzalez]

Summary

Projects can now be updated by a webhook. A push to the repository on GitHub, GitLab or Bitbucket Data Center triggers the same update the Sync button does, so the local copy of the project follows the repo the moment it changes, without polling schedules and without paying the "Update Revision on Launch" penalty on every job launch.

• New Enable Webhook option in the project form, same workflow as job templates: pick the service, save, and configure the generated URL and key in the repository
• Only push and tag push events start a sync (GitHub push, GitLab Push Hook/Tag Push Hook, Bitbucket DC repo:refs_changed/mirror:repo_synchronized), anything else is acknowledged with a 200 and ignored
• Optional Webhook Ref Filter: an fnmatch pattern (refs/heads/main, refs/heads/release-*) so only pushes to matching refs sync the project. Empty (the default) syncs on any push
• Duplicate deliveries are dropped: project updates record webhook_service and webhook_guid, the same dedupe jobs already do
• There is no webhook credential for projects, a sync has no status to post back, so projects only take the service/key part of the mixin

Bring your own webhook key

While wiring the UI for this it became obvious that the always-server-generated key does not play well with managing the controller as code: every time the resource is re-applied the key changes and someone has to update the repository webhook by hand.

So webhook_key is now also writable (write only) on projects, job templates and workflow job templates:

• Supply a key and it is kept as is, so the same secret can live in a vault and be applied to both the repository and the controller by automation
• Leave it blank and the behavior is exactly what it was: a new key is generated whenever the webhook service is set or changed
• Blanking the key of an active webhook generates a fresh one
• The key is never returned on the resource itself, reading it still goes through the webhook_key endpoint and its permission check, and copies of a resource always get their own key
• The key field in the UI is now an editable input with the same semantics

Design notes

• WebhookKeyTemplateMixin (service + key + rotation) extracted from WebhookTemplateMixin, which now inherits from it and adds the credential. No behavior change for templates
• The existing receivers gained a projects model kwarg. Project requests short circuit into handle_project_sync(), which fires create_project_update() with launch_type: webhook instead of building a unified job with payload extra_vars, so the sync honors the project's configured branch/refspec exactly like the Sync button
• get_event_ref_name() resolves the symbolic pushed ref per service for the filter, next to the existing get_event_ref() commit hash lookup
• Validation: manual projects cannot enable webhooks, and a webhook key cannot be set without a webhook service
• One migration (0201). Add conditional workflow connectors based on job artifacts (#505) #561 also carries a 0201, whichever lands second gets renumbered
• Docs: user guide section and the webhook_key endpoint help text
• Tests: functional coverage for the new receiver paths (signed GitHub HMAC and GitLab token deliveries, dedupe by guid, ref filter matrix, permission checks on the key endpoint, custom/blank key semantics, copy gets its own key) plus UI jest tests for the project subform and the editable key

This PR is independent from #561 and #562 and mergeable in any order relative to them.

Pull request overview

Adds webhook-driven project sync support (GitHub/GitLab/Bitbucket DC) and extends existing webhook key handling so keys can be user-supplied (write-only) and preserved for “controller-as-code” workflows, while keeping secrets retrievable only via the dedicated webhook_key endpoint.

Changes:

• Add project webhook receivers that trigger SCM sync on push/tag events with optional ref filtering and best-effort deduplication.
• Extract WebhookKeyTemplateMixin to share service/key/rotation semantics across projects and templates; make webhook_key writable (write-only) for projects, job templates, and workflow job templates.
• Extend UI + docs + functional/UI tests to support editable webhook keys and project webhook configuration (including ref filter).

Do we need the webhook ref filter field? Since we already have a branch field, seems like we could check and see if there is a branch set. And if so then only sync if scm_refspec == os.path.basename(ref_name);
