feat(review): submit interactive (ConPTY) work for review

An embedded ConPTY session leaves its worktree changed but never touches
task status, so hand-driven work had no path into the review/merge flow.

Add SubmitTaskForReview: commit the worktree (same auto-commit as a headless
run), then transition Idle/Failed -> WaitingForReview via the new
TaskStateService.SubmitInteractiveForReviewAsync. Approve then merges it.

Surfaces: a 'Submit for review' button in the detail work console (shown for
an Idle/Failed task with a worktree) and on the ConPTY Command Center pane
header (task-based panes; closes the pane on success). Tests cover the new
transition (Idle/Failed accepted, Running/Queued/Done/Review rejected).
