digest: report the day the player actually played

The morning digest looked up log entries by e.CurrentDay - 1, which
assumed the day rollover happens in deliverBriefing. That only holds for
legacy UTC-anchored runs; event-anchored expeditions roll current_day at
night camp, so by 06:00 CurrentDay is already the day that is starting
and the digest reported a near-empty day. Window on the last briefing
timestamp instead, which also covers nights the autopilot never camped.

Also count real rooms out of the auto-walk summary instead of counting
ticks, and only emit the site footer when the Pete seam is on, since the
roster push is what creates the page the link points at.
