feat(tui): full event history, approval-decision events, status bar

- Events were hard-capped to the last 7 per session in addEvent, so the
  e-inspector and EVENTS panel could never show more. Raise to 1000
  (effectively all, bounded); the EVENTS panel now shows the latest that
  fit (tail), and the inspector scrolls a window around the selection
  with a position indicator.
- The TUI had no approval.resolved handling at all — the decision frame
  was ignored and pending only cleared on session.resumed. Add the
  constant + case: clear the gate and record an ApprovalResolved event
  (APPROVED/REJECTED/AUTO_APPROVED + reason) into the stream.
- Status bar now shows the current stage and session status alongside the
  name. Relabel the cryptic "N bg" badge to "N elsewhere".
