Fix: Proper Controller extension and test route

- Fixed AdminController to extend OCP\AppFramework\Controller
  - Annotations (@NoAdminRequired, @NoCSRFRequired) now work
  - Proper parent::__construct() call
- Added test route /admin/test for debugging
  - Returns JSON to confirm controller works
  - Helps diagnose routing vs permission issues
- Simplified routes to essential ones only
  - admin#index and admin#test

This should resolve 'Access forbidden' for system admin users.
The key fix was extending the proper Controller base class.
