feat(console): touch-mode setting + request-access pairing + polish

Extend the gamepad/console shell (pf-console-ui) to parity with the other clients:

- Settings gain a Touchscreen → Touch mode row (Trackpad / Direct pointer /
  Touch passthrough), the one couch-relevant Settings field the screen lacked.
- The pair screen adds the no-PIN delegated-approval path: a "Request access"
  action (only when the host advertises a fingerprint to pin) opens a connect the
  host PARKS until the operator approves this device, then persists it as paired.
  A role-based row model keeps the cursor off stale indices; manual hosts stay
  PIN-only, matching the desktop shells.
- Threads request_access through OverlayAction::Launch and ConnectIntent; the
  shell shows a "Waiting for approval…" takeover, and the session binary parks on
  a 185 s budget (PendingApproval → persist-as-paired via on_connected).

Auto-wake (WoL) was already implemented end-to-end and is left as-is.
