Kill design-only mock surfaces + wire real offline indicator

P1 — cut showcases:
- Delete gallery.tsx (Primitives) and StatesScreen/Specimen from states.tsx
  (keep the reusable EmptyState/OfflineBanner/ModelAwayState).
- Delete placeholder-screen.tsx ('built in a later phase' stub).
- app-shell: drop the states/primitives views, the dev-rail block, the
  PHASE/TITLE maps, the INBOX_UNREAD=3 fixture fallback, and the now-dead demo state.

P2 — real connectivity:
- Replace the fake 'toggle the connection (demo)' button with a live status dot
  derived from the reconcile: green online, red when serving the stale cache
  (gitea unreachable), amber while connecting. OfflineBanner + chat offline now
  reflect real state, not a manual toggle.
