feedback1 integrate: ticker lines by broadcast priority; AI 托管 keeps a human's items out of temp

- the strip queues by the official broadcast priority (BOSS_HIT 30 > CHAR_DAMAGE 20 > SHOP_LEVEL 11 > ...),
  match-flow notices at 25, never cutting the line on screen short
- on a human seat under AI 托管 an item left in temp with a full hand gets a hand slot (a bench operator sold)
