Enhance timetable functionality and UI integration

- Updated protocol documentation to include new `classId` and `roomLabel` fields in the timetable API responses.
- Added classes and rooms to the timetable response structure, improving data accessibility for client applications.
- Enhanced the UI components to display timetable information, including class and room details, in the management and people panels.
- Implemented functionality to fetch and display personal timetables for individuals, ensuring a comprehensive view of schedules.
- Revised localization strings to support new timetable features and improve user experience.
- Added tests to validate the new timetable functionalities and ensure robustness in handling timetable data.
