feat: Production-ready Docker infrastructure with Directus CMS

- Add separated Docker Compose architecture (astro/infrastructure/override)
- Implement Directus + PostgreSQL with pinned versions (10.12.0/15.5-alpine)
- Add comprehensive database safety protections and backup scripts
- Configure production-ready NGINX reverse proxy setup
- Add container names, labels, and enhanced healthchecks
- Remove fallback environment variables for explicit production config
- Include log rotation and monitoring improvements

Infrastructure deployment:
- npm run docker:infrastructure:up (one-time setup)
- npm run docker:astro:up (regular deployments)
- npm run db:backup/restore/status (database management)
