QA appointments test

[Copilot]

Pull request overview

Adds initial QA/Jest coverage for appointment business validation and sets up a TypeScript/ESM Jest environment for the server.

Changes:

• Extend AppointmentTypeDB with optional “populated” fields used by appointment response formatting (teacherName, studentName, studentProfileImageUrl).
• Switch server Jest configuration to ts-jest ESM and restrict test discovery to **/__tests__/**/*.test.ts.
• Add MongoDB in-memory test database setup + helpers and introduce basic smoke tests + appointment business validation/CRUD tests.
