feedback1 WD: late views keep the form in the client, 重生 clears statuses, blocked 隐匿 drawn solid

- render/app.js: the views' unit info is built by the exported renderInfo(UnitInfo), which now keeps `form`;
  addInfo dropped it, so a view built from fieldMeta (a teammate's field watched later, 联防 observers, a
  reconnect) still drew the first form. Tested through renderInfo (fake PIXI) and the real enterBattle(meta)
  path in headless Chrome (opt-in).
- content/enemies.js: rebirthCleanse at every 重生 (reborn, husk, statue): operator-applied buffs and
  source-less statuses go, own talents / enemy-given buffs / field state stay (PRTS 特殊机制 §重生). A 逐火
  knocked out while feared is no longer an unblockable ember.
- snapshot.js: an enemy's stealth bit only while its 隐匿 is on (not blocked, not revealed).
- Docs: area damage reaching an unblocked 隐匿 enemy is documented as an engine deviation (PRTS 作战机制
  §AOE伤害判定), not as the rule.
