kyle 6c3f017a9e feat: Complete Docker containerization with production-ready setup
Implements comprehensive Docker containerization for the entire VIP Coordinator
application, enabling single-command production deployment.

Backend Containerization:
- Multi-stage Dockerfile (dependencies → builder → production)
- Automated database migrations via docker-entrypoint.sh
- Health checks and non-root user for security
- Optimized image size (~200-250MB vs ~500MB)
- Includes OpenSSL, dumb-init, and netcat for proper operation

Frontend Containerization:
- Multi-stage Dockerfile (builder → nginx)
- Nginx configuration with SPA routing and API proxying
- Security headers and gzip compression
- Optimized image size (~45-50MB vs ~450MB)
- Health check endpoint at /health

Infrastructure:
- docker-compose.prod.yml orchestrating 4 services:
  * PostgreSQL 16 (database)
  * Redis 7 (caching)
  * Backend (NestJS API)
  * Frontend (Nginx serving React SPA)
- Service dependencies with health check conditions
- Named volumes for data persistence
- Dedicated bridge network for service isolation
- Comprehensive logging configuration

Configuration:
- .env.production.example template with all required variables
- Build-time environment injection for frontend
- Runtime environment injection for backend
- .dockerignore files for optimal build context

Documentation:
- Updated README.md with complete Docker deployment guide
- Quick start instructions
- Troubleshooting section
- Production enhancement recommendations
- Updated project structure diagram

Deployment Features:
- One-command deployment: docker-compose up -d
- Automatic database migrations on backend startup
- Optional database seeding via RUN_SEED flag
- Rolling updates support
- Zero-config service discovery
- Health checks prevent premature traffic

Image Optimizations:
- Backend: 60% size reduction via multi-stage build
- Frontend: 90% size reduction via nginx alpine
- Total deployment: <300MB (excluding volumes)
- Layer caching for fast rebuilds

Security Enhancements:
- Non-root users in all containers
- Minimal attack surface (Alpine Linux)
- No secrets in images (runtime injection)
- Health checks ensure service readiness
