refactor(品牌工具页): 历史轮询抽为 useHistoryPolling

QueryAsin / Withdraw / PatrolDelete 三页逐字相同的 startHistoryPolling /
stopHistoryPolling 收敛为 shared/composables/useHistoryPolling：定时器走各页
categorized-timers（category 固定 history-poll），间隔默认主轮询的 2 倍。
categorized-timers 补 CategorizedTimers 类型导出；补注入式假定时器单测 5 例。

净减约 40 行；vue-tsc 构建与 695 个前端单测通过。
