feedback7 dober: the Final Assault and the Hidden Core pay a 战术特训 card's perfect-battle coins, they paid kill coins only (PR #353 by @Sukvii); golden: unchanged

Seen: Match._settleBossBounties banked only the kill coins of the boss field (pp.coins). A perfect-payout bounty (a
战术特训 card, from the 杜宾 Art 教鞭) has its enemies spawned in the Final Assault / Hidden Core like any bounty with
battles left, and used a battle there, but its coins were never paid — SETTLE pays them after every normal battle.
Official: PRTS 杜宾 "<教鞭>：使用后为下场战斗添加额外敌人，若自身战斗完美作战可获得资金" and the cards' "若各自行动阶段就达成完美作战，获得N资金"
have no boss-battle exception. The condition is [ASSUMED]: the team won (the first end the server registered), the result
is a real one (not the synthetic stand-in of a field that never reported) and the player's own field let no counted enemy
through; paid once per player, spent in the Hidden Core's prep with the kill coins.
Now: _finishFinal reads the victory before the per-field loop and hands _settleBossBounties a `perfect` flag.
Tests: clientCombat.test.js (the held 'cleared' result pays once, a duplicate never twice; six eligibility cases:
team win / synthetic / own leak / uncounted leak / forced team defeat), followups.test.js (R14 -> R15 income and the Hidden
Core; a boss win with an own leak keeps the kill coins only). Both fail on the parent.
Golden: unchanged (matches: 18 scenarios match).
