feat: add staff certificates feature with pubspec configuration

- Created pubspec.yaml for the staff_certificates feature with dependencies including flutter_bloc, equatable, get_it, and flutter_modular.
- Established paths for KROW dependencies: design_system, core_localization, krow_domain, krow_core, and krow_data_connect.
- Added firebase_auth and firebase_data_connect as dependencies.
- Generated pubspec.lock file to lock dependency versions.
