De-mock Settings + empty Capture braindump + resolve connection status

More static mocks found by poking the live app:

- Settings was ~80% mock: a fake Sync card (webhook endpoint :48731, poll
  fallback, 'last reconcile 3.2s · 500 issues'), a fake dual-model 'router'
  (gemma-4b/qwen-72b with hardcoded URLs), and an unwired Rituals card. Replaced
  with honest/live content: the Sync card now describes the real on-demand
  reconcile + stale-cache model; the Model card shows the actual probed model
  from model.status(); dropped Rituals and the duplicate 'Forget' button.
- Settings showed 'Not connected' while the app was clearly connected: config:get
  returned only the *saved* config, so a .env.local/env connection read as null.
  It now falls back to a public view of the resolved connection — Settings and
  the rail host label reflect the real christian/commitea connection.
- Capture braindump was pre-filled with a fake example ('auth is flaky…'); now
  starts empty with just the placeholder.

Verified live: Settings shows christian/commitea connected + google/gemma-4-26b
reachable; Capture empty; a live Reginald chat turn runs the agent loop.
