- Removed data_connect package from mobile pubspec.yaml.
- Added documentation for V2 profile migration status and QA findings.
- Implemented new session management with ClientSessionStore and StaffSessionStore.
- Created V2SessionService for handling user sessions via the V2 API.
- Developed use cases for cancelling late worker assignments and submitting worker reviews.
- Added arguments and use cases for payment chart retrieval and profile completion checks.
- Implemented repository interfaces and their implementations for staff main and profile features.
- Ensured proper error handling and validation in use cases.
