Implement a more robust Config (#60)

* Implement a more robust Config

This moves the configuration variables from the `.env` file to a new `bewcloud.config.ts` file. Note that DB connection and secrets are still in the `.env` file.

This will allow for more reliable and easier personalized configurations, and was a requirement to start working on adding SSO (#13).

For now, `.env`-based config will still be allowed and respected (overriden by `bewcloud.config.ts`), but in the future I'll probably remove it (some major upgrade).

* Update deploy script to also copy the new config file
