feat: Introduce CoverageWorker entity and update coverage repository

- Added CoverageWorker entity to represent worker status and check-in information.
- Updated CoverageRepositoryImpl to utilize CoverageWorker and its status.
- Removed legacy coverage_entities.dart file and replaced references with krow_domain imports.
- Enhanced coverage statistics calculations based on new worker status logic.
- Updated UI components to reflect changes in worker status representation.
- Modified acceptance of shifts to align with new status definitions.
- Cleaned up QA testing checklist to remove outdated items and clarify requirements.
