pet.trezy.resolveFeeding

Settle what happened in the terrarium while nobody was watching, and report the state feeding needs. Called on load. HappyView has no scheduler — the only job trigger is job.run:<type>, fired by jobs.create — so an absence is replayed here rather than ticked by a cron. The player cannot tell the difference: they close the tab with four morsels down and come back to find the pets fed and one morsel left. What they gain is that the gap is computed at the moment it can be REPORTED, and that resolution runs while their OAuth session is definitely alive, which a background job could not rely on.
