Add comment-json dependency for parsing HuJSON (JSON with comments and trailing commas) used by Headscale ACL policies. Introduces app/utils/acl-editor.ts with typed interfaces for ACL policy entities and pure functions for parsing, serializing, and mutating policy sections (rules, groups, hosts, tags, SSH rules). Comment metadata is preserved through mutations via comment-json's assign helper. Includes 45 unit tests covering parsing, round-trips, comment preservation, trailing comma handling, and all mutation functions.

Builds on #548 and adds the interactive visual editor as a new tab on the ACL page.
Two generic components —
ArraySection<T>andRecordSection<V>— handle all shared CRUD mechanics (add/edit/remove dialogs, list rendering). Five section instances built on top: ACL Rules, Groups, Hosts, Tag Owners, SSH Rules.Edits stay in-memory and sync with the code editor tab. Nothing is saved to Headscale until the user clicks "Save". Record renames use remove+set to keep logic simple.
comment-jsonassign()preserves HuJSON comment metadata throughout.Also fixed a pre-existing type error in
tests/integration/api/nodes.test.ts.PR 2 of 3 for the visual ACL editor (#286):
Thanks to @simone-gasparini for the initial work in #404.
