feedback5 WE1: Misery's S1 / S2 run as deploy-timed duration skills (activateOnDeploy), not a passive holding a timed buff (follow-up 12)

The 补位 stand-in Misery (char_615_acspec): S1 物理的服从 and S2 战争的恭顺 are PASSIVE / ON_DEPLOY with a 10 s duration;
PR #109's deploy-timed contract runs such skills as duration skills started by every deployment, with their own
skillStart / skillEnd (as 宴 S2, 斯卡蒂 S2, 缄默德克萨斯 …).

- standin-acspec.js: S1 / S2 = kind 'duration', activateOnDeploy, no SP, trigger NEVER, their mods for the duration;
  二象命末 reads "S1 running". S3 空间的归依 stays a passive with its deploy hook. Numbers unchanged.

Golden: standin-01, standin-06 (Misery for 缄默德克萨斯, S2): her skill casts 0 → 14 / 12, skillStart / skillEnd counts,
'skill' events and snapshot hashes; every damage, kill and HP unchanged. Others unchanged.

Tests: test/content/standin_acspec.test.js updated on purpose (the S1 / S2 lifecycle); golden-standins, backups pass.
