🔨 fix: Custom Role Permissions (#12528)
* fix: Resolve custom role permissions not loading in frontend

Users assigned to custom roles (non-USER/ADMIN) had all permission
checks fail because AuthContext only fetched system role permissions.
The roles map keyed by USER/ADMIN never contained the custom role name,
so useHasAccess returned false for every feature gate.

- Fetch the user's custom role in AuthContext and include it in the
  roles map so useHasAccess can resolve permissions correctly
- Use encodeURIComponent instead of toLowerCase for role name URLs
  to preserve custom role casing through the API roundtrip
- Only uppercase system role names on the backend GET route; pass
  custom role names through as-is for exact DB lookup
- Allow users to fetch their own assigned role without READ_ROLES
  capability

* refactor: Normalize all role names to uppercase

Custom role names were stored in original casing, causing case-sensitivity
bugs across the stack — URL lowercasing, route uppercasing, and
case-sensitive DB lookups all conflicted for mixed-case custom roles.

Enforce uppercase normalization at every boundary:
- createRoleByName trims and uppercases the name before storage
- createRoleHandler uppercases before passing to createRoleByName
- All admin route handlers (get, update, delete, members, permissions)
  uppercase the :name URL param before DB lookups
- addRoleMemberHandler uppercases before setting user.role
- Startup migration (normalizeRoleNames) finds non-uppercase custom
  roles, renames them, and updates affected user.role values with
  collision detection

Legacy GET /api/roles/:roleName retains always-uppercase behavior.
Tests updated to expect uppercase role names throughout.

* fix: Use case-preserved role names with strict equality

Remove uppercase normalization — custom role names are stored and
compared exactly as the user sets them, with only trimming applied.
USER and ADMIN remain reserved case-insensitively via isSystemRoleName.

- Remove toUpperCase from createRoleByName, createRoleHandler, and
  all admin route handlers (get, update, delete, members, permissions)
- Remove toUpperCase from legacy GET and PUT routes in roles.js;
  the frontend now sends exact casing via encodeURIComponent
- Remove normalizeRoleNames startup migration
- Revert test expectations to original casing

* fix: Format useMemo dependency array for Prettier

* feat: Add custom role support to admin settings + review fixes

- Add backend tests for isOwnRole authorization gate on GET /api/roles/:roleName
- Add frontend tests for custom role detection and fetching in AuthContext
- Fix transient null permission flash by only spreading custom role once loaded
- Add isSystemRoleName helper to data-provider for case-insensitive system role detection
- Use sentinel value in useGetRole to avoid ghost cache entry from empty string
- Add useListRoles hook and listRoles data service for fetching all roles
- Update AdminSettingsDialog and PeoplePickerAdminSettings to dynamically
  list custom roles in the role dropdown, with proper fallback defaults

* fix: Address review findings for custom role permissions

- Add assertions to AuthContext test verifying custom role in roles map
- Fix empty array bypassing nullish coalescing fallback in role dropdowns
- Add null/undefined guard to isSystemRoleName helper
- Memoize role dropdown items to avoid unnecessary re-renders
- Apply sentinel pattern to useGetRole in admin settings for consistency
- Mark ListRolesResponse description as required to match schema

* fix: Prevent prototype pollution in role authorization gate

- Replace roleDefaults[roleName] with Object.hasOwn to prevent
  prototype chain bypass for names like constructor or __proto__
- Add dedicated rolesList query key to avoid cache collision when
  a custom role is named 'list'
- Add regression test for prototype property name authorization

* fix: Resolve Prettier formatting and unused variable lint errors

* fix: Address review findings for custom role permissions

- Add ADMIN self-read test documenting isOwnRole bypass behavior
- Guard save button while custom role data loads to prevent data loss
- Extract useRoleSelector hook eliminating ~55 lines of duplication
- Unify defaultValues/useEffect permission resolution (fixes inconsistency)
- Make ListRolesResponse.description and _id optional to match schema
- Fix vacuous test assertions to verify sentinel calls exist
- Only fetch userRole when user.role === USER (avoid unnecessary requests)
- Remove redundant empty string guard in custom role detection

* fix: Revert USER role fetch restriction to preserve admin settings

Admins need the USER role loaded in AuthContext.roles so the admin
settings dialog shows persisted USER permissions instead of defaults.

* fix: Remove unused useEffect import from useRoleSelector

* fix: Clean up useRoleSelector hook

- Use existing isCustom variable instead of re-calling isSystemRoleName
- Remove unused roles and availableRoleNames from return object

* fix: Address review findings for custom role permissions

- Use Set-based isSystemRoleName to auto-expand with future SystemRoles
- Add isCustomRoleError handling: guard useEffect reset and disable Save
- Remove resolvePermissions from hook return; use defaultValues in useEffect
  to eliminate redundant computation and stale-closure reset race
- Rename customRoleName to userRoleName in AuthContext for clarity

* fix: Request server-max roles for admin dropdown

listRoles now passes limit=200 (the server's MAX_PAGE_LIMIT) so the
admin role selector shows all roles instead of silently truncating
at the default page size of 50.
