Flat-list layout didn't scale well once auto-discovery filled Apps and
Service Networking with a dozen+ cards each. Splits the dashboard:
Main — Monitoring, AI Systems, Apps, Media, Games, UltraSeedbox
Infra — three per-site hardware groups
Plumbing — Service Networking (dockge x5, traefik, adguard, etc.)
Row counts set to 4 columns on dense groups so they render as grids
rather than vertical walls.
Reorganize the gethomepage dashboard from site-based (PFI-ANA, ESH, NH3)
to function-first grouping (Monitoring, AI Systems, Apps, Media, Games,
Infra-<site>, Service Networking). Canonical config now tracked in
configs/homepage/ with Plex/Jellyfin widget keys moved to env
substitution.
Label sweep across fleet compose files:
- beszel, dozzle, backrest -> Monitoring
- rest-server-ana -> Service Networking
Healthcheck fixes (previous wget/curl paths broke on distroless +
--private-repos 401):
- beszel hub: /beszel health --url ...
- beszel agent: /agent health (newly added)
- rest-server: nc -z localhost 8000 (TCP probe)
Group name originally "Wiring / Plumbing" collapsed to single-word group
on homepage's parser; renamed to "Service Networking" everywhere.
