fix: database migration and routing issues for production

- Add migration to fix email_templates column structure after language migration
- Add migration to ensure default email templates exist
- Create diagnostic script to check database issues
- Fix docker-compose configuration for proper routing without path stripping

The backend expects routes with /api prefix, so removing the stripprefix
middleware allows proper routing to work.
