feedback7 R22-GHSIM: 信仰搅拌机 S1 reloads the latest-deployed 拉特兰 ammo user on his 8 surrounding tiles, not the nearest (GitHub #325, PR #329 by @IceCodeNew, re-implemented); golden: unchanged

PRTS 信仰搅拌机 S1 备注: 「补弹范围为周围8格，仅选择可补弹的干员为目标，优先选择最后部署的干员」. The candidates (his own
拉特兰 operators within 1.5 tiles — the 8 surrounding tiles — whose ammo skill runs) are now sorted by the battle-wide
deploySeq, latest first (a redeploy is a new deployment), ties by unit id; until now by distance [ASSUMED]. The unused
detmath hypot import goes. Golden: unchanged (no corpus battle has two such candidates in a different order).
