Add a second tab in the node Icon picker to choose from the ~2250 brand icons hosted by homarr-labs/dashboard-icons (Plex, Sonarr, Home Assistant, etc.) served via jsDelivr CDN. The Generic tab keeps the existing lucide picker unchanged. Storage uses a 'brand:<slug>' prefix on custom_icon, so existing nodes referencing lucide keys keep working with zero migration. A new resolveCustomIcon helper returns a discriminated union (lucide | brand) and a NodeIcon component centralizes rendering for both kinds. Includes a manifest fetch script (scripts/fetch-dashboard-icons.mjs) and a checked-in dashboardIcons.json snapshot.
