* Grafana Cloud migration, adding dashboards, fleet, alloy and synthetics
* modulize stuff now that we have multiple substantial things in here
* provider updates and new secrets
* remove grafana and prometheus from ansible
* fix: actually decomission nextcloud and TWDNE
* ignore spaces in lint and remove dns for the services
* linting on the linting config wasn't linting the lints
alerting is handled by grafana, not alertmanager. removed the
stale reverse proxy block from caddyfile template and updated
caddy + prometheus docs to reflect grafana-only alerting.
