feat: implement domain guard for commission calculation and enhance representation dashboard

- Added domain guard in CommissionService to ensure commission is calculated only when the appointment is booked under the same representation as the doctor.
- Updated RepresentationController to filter statistics by representation, ensuring accurate data is shown for each representative.
- Introduced new endpoints for the representation dashboard to provide summary statistics, doctor performance, and financial reports.
- Created new pages for RepresentationFinance and RepresentationSettlement to display financial data and allow for settlement requests.
- Added migration to include booking_representation_id in appointments for tracking the representative under which the appointment was booked.
