feat(webapp): register wardrobe in workbench app-registry

The Kleiderschrank module shipped end-to-end (M1–M5 + M4.1) but was
never surfaced on the workbench homepage — it was reachable only via
direct /wardrobe URLs. This adds the tile so users can add it to a
scene and open it from the launcher like every other module.

- apps.ts: registerApp({ id: 'wardrobe', name: 'Kleiderschrank',
  color: #e11d48, icon: CoatHanger }) — list view loads
  $lib/modules/wardrobe/ListView.svelte (tab switcher Kleidung /
  Outfits). Detail routes stay SvelteKit-based
  (/wardrobe/garment/[id], /wardrobe/outfit/[id],
  /wardrobe/compose/[[outfitId]]) so the workbench only needs the
  root list slot.
- categories.ts: wardrobe → 'creative' (next to picture, library,
  playground, quiz).

Color matches the shared-branding entry in mana-apps.ts. Icon is the
phosphor CoatHanger (there is no bare "Hanger" in phosphor-svelte).
