feedback1e WP: live attack range on the battle card; 烛煌 S3 splash 1.7

Community report "干员烛煌开启3技能时候攻击范围不会变". The sim already attacked
with S3's 4-11 while it ran (real matches, and every attack-range change of
the mode); what stayed the same was the battle detail card: its 攻击范围
mini-map kept the base 3-1 grid while the live stats beside it moved.

- Battle._refreshRange keeps the relative grid behind rangeKeys as
  unit.liveRangeGrid (targeting.js extendedGrid: rangeExtend grown on);
  shared/protocol.js unitStatsEntry carries it as `range`; the detail card
  draws it (cardRangeGrid) in battle and in the prep preview, and names a
  whole-field range (纯烬艾雅法拉 S3) 全场 instead of drawing it.
- 烛煌 S3 "攻击变为群体攻击" is one target + a 1.7 splash (PRTS 技能3 备注
  "攻击溅射半径1.7"), not every enemy inside 4-11; the burst bonus hits
  every enemy of the attack; a burn burst's +2 ammo stops at the skill's
  ammo ("补充后的弹药数量无法超过上限").
- Tests: test/sim/feedback1e-skillrange.test.js (S3 range, splash, ammo
  cap, live grid, the audit of every attack-range change, a real spec),
  test/ui/feedback1e-range.test.js (the card).
