feat: refactor clinic management into a dedicated settings tab

- Removed MyClinicPage and redirected its functionality to a new ClinicDoctorsPage.
- Created ClinicDoctorsManager component for managing doctors and invitations within the settings layout.
- Updated backend permissions to allow clinic owners to detach doctors, alongside admins.
- Adjusted API documentation to reflect new permission structure.
- Updated tests to cover new functionality and permissions.
- Modified sidebar and settings menu to reflect the new structure and role-based visibility.
