Refactor clock-in feature: Introduce validation pipeline and interaction strategies

- Added a validation pipeline for clock-in actions, including geofence, time window, and override notes validators.
- Created a context class for passing validation data and results.
- Implemented check-in interaction strategies for swipe and NFC methods, encapsulating their UI and behavior.
- Removed redundant utility functions and centralized time formatting in a new utility file.
- Enhanced the notification service to handle clock-in and clock-out notifications separately.
- Updated the ClockInBloc to utilize the new validation and notification services.
- Cleaned up the ClockInActionSection widget to use the new interaction strategies and removed unnecessary listeners.
