feat: Enhance appointment management by decoupling online booking toggle for admin context

- Introduced management mode for appointment slots, allowing doctors, admins, and clinic managers to view and book slots regardless of the online booking status.
- Updated SlotCalculatorService to accept a management context parameter, bypassing online booking restrictions.
- Modified appointment-related endpoints to handle management context and ensure proper authorization checks.
- Added tests to verify that management users can access slots even when online booking is disabled, while public users are still restricted.
- Improved documentation for API endpoints to reflect new management parameters and behaviors.
