fix: improve container startup reliability and logging

- Increase healthcheck start period from 40s to 120s for slow migrations
- Simplify healthcheck to check nginx root instead of Django API
- Add verbose logging to supervisord and start-django.sh
- Increment CACHEBUST to 3

This gives Django more time to run migrations and provides better debugging visibility.
