feedback1e WR: 阵法术师 / 轰击术师 strike every enemy in range (卡涅利安 E3)

Community report E3 "卡涅利安的攻击不是真群攻" was real: the phalanx trait
"技能开启时攻击造成群体法术伤害" was read as one bolt at the priority target
plus a 1.1-tile splash, so spread enemies took one hit per attack (act2 m01,
round 10: 2.3 of 12.4 enemies on her range per attack, never all).

Officially a 阵法术师 attack hits every enemy inside the attack range at
once, the same damage near and far (Arknights Terra Wiki, Phalanx Caster;
PRTS 林 S3 note; PRTS 作战机制 AOE), and so does the 轰击术师 line
(Terra Wiki, Blast Caster; PRTS 作战机制: 伊芙利特's 炎爆 is a range-locked
AoE). The 扩散术师 keep their 1.1-tile splash around the target.

- professions.js: phalanx and blastcaster get allInRange + rangeAoe
  (instant 'beam' hits, no projectile) instead of the 1.1 splash.
- 卡涅利安 S3 食噬之印: ATK climbs in 1 s steps to the full bonus at 20 s
  (PRTS note) instead of continuously over the 21 s duration.
- fx.js: phalanx / blastcaster leave the splash-ring list.
- Tests: real battles counting damaged enemies per attack for every
  phalanx skill, both blast casters, a splash-caster guard, a real stage
  and wave, the S3 ramp; opt-in headless-Chrome check of the strikes.
- SIM.md profession rows and kit comments updated.
