| Legacy /api/admin/config backward compatibility (Task 17)
|--------------------------------------------------------------------------
|
| The pre-existing admin config API (AdminApiController@getConfiguration /
| @updateConfiguration) must keep working after the config-cache refactor.
| The enable_cc gate (abort_unless(config('instance.enable_cc'), 400)) was
| REMOVED, so an authorized admin now gets a 200 unconditionally — these tests
| lock that in so a future change cannot silently regate the legacy surface.
|
| Routes (routes/api.php, unchanged):
|   GET  /api/admin/config          getConfiguration   (admin:read)
|   POST /api/admin/config/update   updateConfiguration (admin:write)
|
| Each item is { name, description, key, state } with state derived via
| config_cache($key). The 5 keys are all ENVCONFIG booleans; under
| .env.testing OPEN_REGISTRATION=true is present+valid, so open_registration is
| env-locked and put() no-ops — the endpoint still returns 200 + current state.
|
| Auth mirrors AdminAccessTest / ScopeTest: Passport::actingAs(admin, [scopes]);
| non-admin / wrong-scope → 404; unauthenticated → 401.
|
| Validates: Requirements 9.1, 9.3
|
