- Updated devfront to recognize 'rp_admin' and 'tenant_admin' as privileged developer roles.
- Added specific forbidden messages for privileged roles in devfront.
- Improved adminfront Worksmobile test reliability across browsers.
- Updated Makefile to skip userfront tests in environments without Flutter SDK.
- Applied lint and format fixes across adminfront and devfront.
