Add comprehensive tests for dose tracking functionality

- Implemented `test_dose_parsing_simple.py` to validate the dose parsing workflow.
- Created `test_dose_save.py` to verify the saving functionality of dose tracking.
- Added `test_dose_save_simple.py` for programmatic testing of dose saving without UI interaction.
- Developed `test_final_workflow.py` to test the complete dose tracking workflow, ensuring doses are preserved during edits.
- Enhanced `conftest.py` with a mock pathology manager for testing.
- Updated `test_data_manager.py` to include pathology manager in DataManager tests and ensure compatibility with new features.
