refactor: Remove Directus infrastructure, simplify Docker deployment

- Remove Directus CMS infrastructure (docker-compose.infrastructure.yml)
- Simplify to Astro-only deployment using existing Supabase backend
- Clean up docker-compose.override.yml to focus on local development
- Update NGINX config to proxy only to Astro app
- Remove Directus-related npm scripts and database management tools
- Streamline deployment guide for Supabase + Astro architecture

Deployment workflow:
- Local: npm run docker:dev (Astro + Supabase hosted)
- Production: npm run docker:astro:up (Astro only)

Benefits:
- Simpler architecture with proven Supabase backend
- Faster deployments (Astro only)
- Zero database downtime
- Reduced operational complexity
