Enhance authentication flow and user role management

- Updated AuthViewModel to hydrate user data from storage on initialization.
- Added method to AuthRepository for retrieving stored customer data.
- Enhanced AuthService to save and retrieve customer data from SharedPreferences.
- Refactored UI components to use context.watch for user role updates in MeetingTimeDialog, TenderDetailActions, and TendersPage.
- Improved navigation logic in final completion pages to handle user interactions more effectively.
