homepage: app-card art, zealot-first order, common uncensored warning, admin identity gate

- Every app card carries hex-clipped art: 19 amber-tinted brand marks
  from the Simple Icons CDN plus 19 improvised monogram SVGs, wired via
  a per-service "art" field; homepage_config.bats pins art presence for
  all 32 apps.
- Model cards render zealot -> dragoon -> archon (registry order pinned
  in the seam).
- Dragoon and zealot share one common uncensored legal warning (adult
  content, harmful/hateful/illegal descriptions, sensitive offensive
  cybersecurity topics, severe legal risk, "don't ruin this server for
  everybody"), hover label on card and docs.
- Archon gets a bordered red permission callout: ask Frank before use.
- SearXNG obfuscation-not-anonymity note moved to a card-level hover
  warning (.svc-warn) and a docs hover note.
- Gitea: self-service signup flow; no need to ask Frank.
- Footer docs/admin/account-settings become glowing bordered buttons;
  the admin button is shown only to homepage-admins members via a new
  Caddy /whoami endpoint echoing the outpost-injected X-Authentik-*
  headers (spoof-proof; the /admin* 403 stays the real gate). e2e pins
  both sides.
- Docs naming swept: Protoss names primary, bracketed api ids, explicit
  note that a future switchover renames the ids themselves.
