👨‍👨‍👦‍👦 feat: Admin Users API Endpoints (#12446)
* feat: add admin user management endpoints

Add /api/admin/users with list, search, and delete handlers gated by
ACCESS_ADMIN + READ_USERS/MANAGE_USERS system grants. Handler factory
in packages/api uses findUsers, countUsers, and deleteUserById from
data-schemas.

* fix: address convention violations in admin users handlers

* fix: add pagination, self-deletion guard, and DB-level search limit

- listUsers now uses parsePagination + countUsers for proper pagination
  matching the roles/groups pattern
- findUsers extended with optional limit/offset options
- deleteUser returns 403 when caller tries to delete own account
- searchUsers passes limit to DB query instead of fetching all and
  slicing in JS
- Fix import ordering per CLAUDE.md, complete logger mock
- Replace fabricated date fallback with undefined

* fix: deterministic sort, null-safe pagination, consistent search filter

- Add sort option to findUsers; listUsers sorts by createdAt desc for
  deterministic pagination
- Use != null guards for offset/limit to handle zero values correctly
- Remove username from search filter since it is not in the projection
  or AdminUserSearchResult response type

* fix: last-admin deletion guard and search query max-length

- Prevent deleting the last admin user (look up target role, count
  admins, reject with 400 if count <= 1)
- Cap search query at 200 characters to prevent regex DoS
- Add tests for both guards

* fix: include missing capability name in 403 Forbidden response

* fix: cascade user deletion cleanup, search username, parallel capability checks

- Cascade Config, AclEntry, and SystemGrant cleanup on user deletion
  (matching the pattern in roles/groups handlers)
- Add username to admin search $or filter for parity with searchUsers
- Parallelize READ_* capability checks in listAllGrants with Promise.all

* fix: TOCTOU safety net, capability info leak, DRY/style cleanup, data-layer tests

- Add post-delete admin recount with CRITICAL log if race leaves 0 admins
- Revert capability name from 403 response to server-side log only
- Document thin deleteUserById limitation (full cascade is a future task)
- DRY: extract query.trim() to local variable in searchUsersHandler
- Add username to search projection, response type, and AdminUserSearchResult
- Functional filter/map in grants.ts parallel capability check
- Consistent null guards and limit>0 guard in findUsers options
- Fallback for empty result.message on delete response
- Fix mockUser() to generate unique _id per call
- Break long destructuring across multiple lines
- Assert countUsers filter and non-admin skip in delete tests
- Add data-layer tests for findUsers limit, offset, sort, and pagination

* chore: comment out admin delete user endpoint (out of scope)

* fix: cast USER principalId to ObjectId for ACL entry cleanup

ACL entries store USER principalId as ObjectId (via grantPermission casting),
but deleteAclEntries is a raw deleteMany that passes the filter through.
Passing a string won't match stored ObjectIds, leaving orphaned entries.

* chore: comment out unused requireManageUsers alongside disabled delete route

* fix: add missing logger.warn mock in capabilities test

* fix: harden admin users handlers — type safety, response consistency, test coverage

- Unify response shape: AdminUserSearchResult.userId → id, add AdminUserListItem type
- Fix unsafe req.query type assertion in searchUsersHandler (typeof guards)
- Anchor search regex with ^ for prefix matching (enables index usage)
- Add total/capped to search response for truncation signaling
- Add parseInt radix, remove redundant new Date() wrap
- Add tests: countUsers throw, countUsers call args, array query param, capped flag

* fix: scope deleteGrantsForPrincipal to tenant, deterministic search sort, align test mocks

- Add tenantId option to AdminUsersDeps.deleteGrantsForPrincipal and
  pass req.user.tenantId at the call site, matching the pattern already
  used by the roles and groups handlers
- Add sort: { name: 1 } to searchUsersHandler for deterministic results
- Align test mock deleteUserById messages with production output
  ('User was deleted successfully.')
- Make capped-results test explicitly set limit: '20' instead of
  relying on the implicit default

* test: add tenantId propagation test for deleteGrantsForPrincipal

Add tenantId to createReqRes user type and test that a non-undefined
tenantId is threaded through to deleteGrantsForPrincipal.

* test: remove redundant deleteUserById override in tenantId test
