Long expeditions D7-b: drive autopilot camp from SimRunner

maybeAutoCamp / pitchAutopilotCamp / pitchBossSafetyCamp now take a
now time.Time so the sim can inject a synthetic clock; tryAutoRun
still passes time.Now().UTC(). SimRunner.RunExpedition advances simNow
by autoRunCooldown per walk and runs the production camp scheduler
after each soft stop (and pitchBossSafetyCamp on stopBossSafety),
dwelling minAutoCampDwell + breakAutoCampIfDue so the next walk can
proceed. Effect: HP-low mid-day rests, base-camp waypoints, Night-camp
rollovers, and boss-safety holds all fire under the sim; D7-a's
tickEventAnchoredRollover shortcut is retained on TickDay for tests
and the pre-cutoff legacy path.
