Subject: [PATCH] fix: add SMTP and missing environment variables to
 docker-compose.yml

- Fix USER_TEMPLATE_IMAGES quoting in .env.example (prevent bash metacharacter issues)
- 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

SMTP variables were defined in .env but not passed to container, causing
email service configuration issues.
