Fix production deploy routing and Traefik project reuse

- pass NEXT_PUBLIC_CARPLACE_URL into the production Docker build
- run the production deploy script after building the image
- support raw or base64 production env secrets during deploy
- copy the production env file into the remote build context
- include homepage in production deploy, pull, and health checks
- use a stable Traefik Compose project name to avoid duplicate proxy containers
