Add meeting schedule state management services and related models

This commit introduces several new services and models to manage the meeting schedule state within localStorage. The MeetingScheduleState class is created to track scheduled teams, absent students, time slot counts, extended teams, and excluded students. Additionally, the IMeetingScheduleStateService interface and its implementation, MeetingScheduleStateService, are added to handle loading and saving state data. The MeetingScheduleClipboardService and MeetingScheduleDataService are also introduced to facilitate clipboard operations and data loading from the database, respectively. These enhancements improve the overall functionality and user experience of the meeting scheduling feature.
