Add infrastructure skeleton for review (refs #21)

Lays out the agreed shape from the design discussion: one flake at the root with three nixosConfigurations (mqtt-ingest, db-host, app-host), vendored Supabase docker-compose pointed at the external db-host, Caddy → Kong → PostgREST/GoTrue, a Go MQTT→Postgres ingester stub, deploy-rs node map, and a Gitea Actions workflow that deploys in db → app → ingest order on push to main. No real implementation yet — every host module has TODOs marking the gaps (real hardware config, actual hostnames, HiveMQ packaging, vendor the full upstream Supabase compose, etc.).
