Part B: infra stacks carry identity — curated Hungarian metadata for cloudflared/traefik/filebrowser (v0.126.0)

- inframeta.go: static display-only map (name/description/Linked) + infraMeta template func;
  filebrowser is the ONLY Linked stack (files.<domain> Megnyitás on the dashboard row;
  the stacks card already links via Subdomains)
- generic infra icon: embedded /static/infra-logo.svg (Lucide-style server, monochrome)
  wired through the app-row FallbackIcon slot + the stacks-card onerror chain
- dashboard rows + app cards: infra name + description + existing Védett chip
- guarded WRONG outcome: no customer link for cloudflared/traefik — render tests count
  exactly ONE https:// link; red-proven (Linked:true on cloudflared → test FAILS)
