Enhance MeetingSchedule component to support student exclusion management

This commit introduces functionality in the MeetingSchedule feature to manage student exclusions during scheduling. The Index.razor component has been updated to include methods for saving and loading excluded students, as well as UI elements for toggling exclusions. Additionally, the TeamScheduler logic has been modified to account for excluded students when calculating overlaps and scheduling teams. These changes improve the flexibility and accuracy of the scheduling process, enhancing the overall user experience.
