- Add all SMTP configuration variables to docker-compose environment
- Add EMAIL service variables (FRONTEND_URL, MAGIC_LINK_EXPIRY, RATE_LIMIT)
- Add JWT and resource limit variables
- Improve environment variable organization with comments

- curl is pre-installed and compatible with Debian slim images
- Consistent with spawner API healthcheck (also uses curl)
