feat: hive card with SVG, outline, edit sheets and catalog settings (Beute L2)

- lib/hive: frontend port of the hive domain (ops, validator, facts,
  layout, follow-ups, describe texts, reason texts) running the backend
  fixtures, API client
- hive card on the colony page (same height as Stammdaten): SVG view,
  accessible outline tree, frame/part sheets with optimistic save,
  conflict sheet, history with past states, init from template or
  another colony, inspection draft mode
- follow-up toasts prefilling feeding and treatment forms (treatment
  end only with an open treatment)
- settings page "Beutensysteme" (hive-systems:manage)
- NumberStepper decimal steps, reactive motion level hook, holo tokens
- spec: owner design decision 2026-10-16 (glass hologram, focus mode)

The SVG view is the fallback; the 3D scene follows in L3.
