feat(ui): move review feedback to the Output tab + review/worktree polish

- Feedback box + a new "Resume session" button move from the Git tab to the
  Output tab; the Git review block keeps Approve & Merge / Park / Cancel / Reset.
- Add a "Parked" chip for Idle tasks that still hold an Active worktree.
- Stop showing the "Session was Cancelled" band on cancel (failed-only now).
- Fix the Worktrees-overview state-chip contrast (dark text on the colour).
