feat: Add group participant request management functionality

- Introduced new endpoints for handling requested participants in groups: - GET /group/participants/requested to retrieve requested participants. - POST /group/participants/requested/approve to approve participant requests. - POST /group/participants/requested/reject to reject participant requests. - Added corresponding methods in the group service to manage participant requests. - Implemented validation for new request types to ensure proper data handling.
