fix(directus): resolve critical deployment issues

- Remove duplicate directus-extensions volume mount (conflict)
- Fix FORCE_FRESH_INSTALL boolean check (handle 'True' from Coolify)
- Optimize healthcheck (10 retries, 60s start period)
- Remove unused named volume definition

All syntax validated:
✅ docker-compose.yaml valid
✅ start.sh syntax OK
✅ Extensions structure correct
✅ SQL schema present
