Refactor doctor name handling across the application

- Removed the "دکتر" prefix from doctor names in various components and API responses to ensure consistency and clarity.
- Updated the AppointmentDetailPage, CommentsPage, DashboardPage, RatingsPage, SecretariesPage, and other relevant files to reflect the changes in doctor name formatting.
- Adjusted API documentation to align with the new naming conventions.
- Implemented validation to prevent the creation of clinics without a name and restricted users to a single clinic.
- Added tests to verify that doctor names are stored without titles and that clinic creation adheres to the new validation rules.
