homepage: icon swaps, clickable tiles, down pulse, header nav, compaction callout

- Icons: Copyparty -> improvised amber folder, Marreta -> crumbling
  wall (bricks + red crack), Calibre-Web -> book, OpenWebUI -> official
  logo.png from openwebui.com, Seerr -> official seerr.dev
  os_logo_filled.svg.
- Tiles with an open link are clickable whole (.panel.clickable: hover
  lift + glow; inner link clicks pass through).
- Any DOWN panel (app tile or model card) gets a red gradient wash and a
  slow pulsing glow (.panel.down, .mi-card:has(.badge.down)).
- docs / admin / account-settings buttons moved from the footer to the
  header (nav.top-links); footer keeps the deployment stamp.
- Zealot compaction advice promoted from the Use paragraph to a bordered
  glowing model.compaction callout (.mi-comp); component seam pinned to
  the new field.

 The live up/down check runs server-side. A checker on Dankclaw probes each backend and writes a same-origin `status.json`. The page fetches only that file and renders the badges. The browser never calls a backend directly. The checker runs as a systemd timer every 3 minutes.
