test(api): add appointment endpoint tests

[miguelm-montano]

Assisted-By: Claude Code

Short description of what this changes or resolves:

Adds API test coverage for the Standard REST Appointment resource, addressing gaps in the API test suite. Currently only 30/172 route+method combinations have tests.

Contributes to #12343

Changes proposed in this pull request:

• Created tests/Tests/Api/AppointmentApiTest.php with tests for:
  • GET /api/appointment (list all appointments)
  • GET /api/appointment/:eid (get single appointment by ID)
  • Proper error handling (404 for missing ID, 401 for unauthorized)
  • Follows the FacilityApiTest pattern as suggested in the coverage gap issue

Coverage impact:

• Before: 30/172 route+method combinations tested (17%)
• After: 32/172 route+method combinations tested (18.6%)
