feat(ux): T5 战斗胜利结算 GP 接线——总量+增量落胜利总结结算(OQ14 口径)

- BattleEndOverlay 新增战利品行(open_victory 可选参 gp_summary;失败侧恒不呈现——GP 总量+增量归胜利总结结算)
- main 两个胜利分支(level_end/standalone_end)装配'战利品 GP +增量 · 合计总量':增量=battle_finished 载荷 gp_dropped,总量=runner.gp 现值(LevelRunner 入账连接先于组合根 handler——读数即战后总量)
- 纯呈现接线,账本语义零改动;账本入账/清零路径零触碰
- 轻闸:冒烟 557/0+ui_probe+ui_click_probe(全冒险含胜利终局)+ui_input_probe 全绿
