fix(store,audit,workspace): usertest low-findings tail (0.72.1)

- Store hero: 'TODAY' badge only for an operator-accepted story; the
  rotating compiled-in fallback deck now says 'FEATURED' (no false
  freshness claim). Policy as a top-level function with unit tests.
- Audit filter chips: standard label typography instead of mono —
  mono stays reserved for paths and identifiers.
- DE chain wording: 'Hash-Kette geprüft' as the one confirmation term
  (audit header now matches the doctor pill); 'intakt' stays the
  state headline. EN was already consistent.
- Workspace switcher: contrast bump for the sealed-area 'stopped'
  label.
