Port mobile design to relay web client

The web client at /app was a single terminal screen — no home view, no
sessions list, no agent picker, no modal system. The Flutter mobile app
has all of those plus a coherent visual language. Port the mobile screens
and modal patterns to the inline-HTML web client so the two surfaces read
as the same product.

What changed:
- Three-view router via window.location.hash: #pair (token redeem +
  4-digit SAS), #home (paired-device card + sessions list + new-session
  FAB), #session/:id (terminal). First load with #loopsy://pair?... auto-
  redeems and lands on #home.
- Modal system mirrors loopsy_modal.dart: showLoopsyDialog() and
  showLoopsySheet() helpers, action variants (text/outlined/primary/
  danger), LoopsyMenuTile rows for picker sheets.
- Sessions list backed by localStorage keys matching mobile/storage.dart:
  loopsy.pairing.v1, loopsy.sessions.v1, loopsy.auto_approve.v1.
- Auto-approve password handshake matches the daemon flow shipped in
  02adb75: cached approveToken used silently, falls back to a password
  dialog that hands sudoPassword to the daemon. Handles auto-approve-
  granted/denied control frames.
- Forget-pairing dialog calls DELETE /device/:id/phones/self for CSO #8
  server-side revoke, then wipes all three localStorage keys.

Preserved: xterm.js terminal, voice input (Web Speech API), compose-box
keyboard handling, WS reconnect logic, summary-capture from first stdin
bytes, session bookkeeping. The terminal view is functionally identical;
only the chrome (back button + session topbar) changed.

Deviations from mobile (unavoidable):
- Pair view uses URL input instead of camera-based QR scan. No CDN
  scanner library; the URL hash carries the token in the typical flow
  anyway, so this only matters for the rare manual-paste path.
- No long-press on session cards (no reliable browser equivalent). The
  kebab is the only path to the session menu.
