* Add CardDav and CalDav servers
This implements the servers, but not the clients (yet). The implementation is essentially a proxy to Radicale (as a container in `docker-compose.yml`), with certain security assurances.
If you're upgrading, basically you'll need to create a new `data-radicale` directory, and everything else should just work.
This will also release v2.3.0 with those enabled by default. Tested with Thunderbird and Apple Calendar + Contacts.
To disable these, simply add the new config details and comment out or don't add the new `radicale` service from `docker-compose.yml`.

* 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
