Check pi liveness per tmux pane and add "Seen" marks to the control board (#1503)

Browse Source 
First step-3 refinement from Jason's daily use. Liveness now lists the
panes of the agent's tmux session and counts it alive only if a pane runs
pi, so killed pi sessions whose tmux session still exists show offline
instead of waiting. A "Seen" button on waiting and error rows stores the
row's lastActivity in <dataRoot>/board/seen.json (clicks only, never
rewritten by a scan, fail closed if corrupt) and drops the row from
"Waiting on you" until the agent writes anything newer; "Unsee" reverses
it. New POST /api/seen route: JSON only, 4 KB limit, 400 on bad input.

Tests: control-board 63/63 (30 new), registry 69/69. Review APPROVED;
receipt docs/plans/reviews/2026-09-12_control-board-step3-seen-marks.md.
