- Add environment-aware CORS and secure cookie support:
* Add secureCookies config to env.ts based on SECURE_COOKIES env var or https detection
* Integrate @elysiajs/cors with credentials and origin configuration
* Update cookie helpers to use SameSite=None; Secure in production
- Wrap expert review update and insert in database transaction for atomicity:
* Ensures diagnosis status update and review insert succeed together
* Rolls back both operations if either fails
* Preserves behavior: only update if status is needs_review, return badRequest if no row updated
