Subject: [PATCH] feat: Add Dockerfile for Railway deployment

Added production-ready Dockerfile:
- Node.js 18 Alpine (lightweight)
- Multi-stage dependency installation
- Health check monitoring
- Non-root user for security
- Production optimizations

Added .dockerignore:
- Exclude node_modules (reinstalled in Docker)
- Exclude .env files (Railway injects env vars)
- Reduce image size
- Faster build times

Railway will now detect project type via Dockerfile instead of guessing from package.json.
This ensures proper build configuration for BullMQ worker.
