fix(P2): 5 priority-2 bug fixes — emoji consolidation, DM safety, pause gap

#10  Redundant coin flip in join_conversation — removed the 50% random
     gate that doubled the V2 engine's own decision to act.

#11  Message-triggered actions skip _autonomous_paused — _check_and_act
     and _check_and_react now bail out immediately when the autonomous
     system is paused (voice session), matching the scheduled-tick path.

#12  Duplicate emoji dictionaries — removed MOOD_EMOJIS and
     EVIL_MOOD_EMOJIS from globals.py (had different emojis from moods.py).
     bipolar_mode.py and evil_mode.py now import the canonical dicts
     from utils/moods.py so all code sees the same emojis.

#13  DM mood can spontaneously become 'asleep' — rotate_dm_mood() now
     filters 'asleep' out of the candidate list since DMs have no
     sleepy-to-asleep transition guard and no wakeup timer.

#15  Engage-user fallback misreports action type — log level raised to
     WARNING with an explicit [engage_user->general] prefix so the
     cooldown-triggered fallback is visible in logs.
