feat: update Docker config for VITE_WORKER_ENV support

- Dockerfile now uses VITE_WORKER_ENV instead of hardcoded worker URL
- docker-compose.yml uses VITE_WORKER_ENV=production
- docker-compose.dev.yml uses VITE_WORKER_ENV=staging (points to dev worker)
- Staging site will use jeffemmett-canvas-dev.jeffemmett.workers.dev
