Introduces group calling capabilities, including group invites and participant lifecycle management. Enhances the existing call system with support for media types (voice/video) and improved participant tracking. - Add `GroupInvite` and `ParticipantJoin/Leave` to `CallService`. - Implement WebSocket handlers for `call_group_invite` and `call_participant_join`. - Update `CallSession` model to support group IDs, media types, and tracking who ended the call. - Integrate `GroupService` into `CallService` via dependency injection. - Add error constants for group call limitations and participant capacity. - Update LiveKit webhook handling to process participant leave events. Refactor grade synchronization to remove semester-based filtering in favor of a more flexible user-based approach and improve GPA summary updates.
