feedback1 WD: forms reach late views, stable enemy shapes, review fixes

- Every form change goes through content setForm(): the unit keeps it (e.form)
  and UnitInfo publishes it, so a view built mid-battle from fieldMeta (a
  watched teammate's field, 联防 observers, a reconnect) starts in the
  current form instead of the first-form model.
- Enemy profile (dmgType) and Unit moving / form are initialised at spawn:
  one object shape for the sim's hot loop (the boss-field bench is back at
  the base speed).
- 转译基底·α: an HP loss cannot knock out its original form (no death clip).
- 假想敌：再生: 1 s 重生 and walking 傀儡 cited from PRTS; shields within 1.8
  as the 再生状态 begins.
- Renderer: a 重生's closing clip (and the ember's stand-up clip) is timed
  from the fx dur to end with it, so the next form attacks on its own clips.
