Information disclosure in env-config file

[RaduCStefanescu]

When viewing the source page of https://prod.stamacasa.ro/env-config.js , an user is able to access the env-config.js of the application which may expose sensitive information about the build environment

I think this is the same issue we had on date-la-zi see this commit

On frontend side, we should make a new artifact/docker image for every environment we need to have and inject all env configs on build time.
