feat: docker-compose for production frontend (#664)

* docker-compose for production frontend

* fix: Remove external Redis port mapping for Coolify compatibility

Redis should only be accessible within the internal Docker network in Coolify deployments to avoid port conflicts with other applications.

* fix: Remove external port mapping for web service in Coolify

Coolify handles port exposure through its proxy (Traefik), so services should not expose ports directly in the docker-compose file.

* server side client envs

* missing vars

* nextjs experimental

* fix claude 'fix'

* remove build env vars compose

* docker

* remove ports for coolify

* review
