nixos/grafana: update and add settings

I went through all categories that were already present in the grafana
module and added most options from the official docs at
https://grafana.com/docs/grafana/v9.5/setup-grafana/configure-grafana/

I also modified the descriptions of some existing options to match the
official docs more closely.

This is the full URL used to access Grafana from a web browser.
This is important if you use Google or GitHub OAuth authentication (for the callback URL to be correct).
This setting is also important if you have a reverse proxy in front of Grafana that exposes it through a subpath.
In that case add the subpath to the end of this URL setting.
