feat: view past sessions, edit session details, log rituals while reviewing

- View any past session as a read-only HUD: /session?id=N (hud(session_id) +
  /session/data?id=); /history rows now link there. Closed sessions show played
  duration + final net; recap link when one exists.
- Edit session details during or after play: poker.update_session (recomputes net
  when buy-in/cash-out change), PATCH /session/{id}, an update_session tool ("venue
  was actually Bellagio", "I bought in for 600"), and an inline ✎ Edit form on the HUD.
- Rituals attach to the most-recent session post-close (poker.review_session_id),
  so scar/confidence/reset work while reviewing after you rack up.
- Edit form is poll-safe (won't clobber mid-edit); past-session view doesn't poll.
- test_modes.py +3 (edit, review rituals, past-session HUD); 49 green.
