fix(admin): 风控 tab 点了没反应 —— tab key 白名单漏登记，并合并为唯一来源

## 现象与根因

风控 tab 渲染得出来、但怎么点都切不过去，且不报错、不白屏。

原因是 tab key 名单在同一文件里写了两遍：
  - isWorkerPlatformTab()（changeTab 的守卫）
  - loadActiveTabPreference()（localStorage 旧选择校验）
新增风控 tab 时只把 'risk-control' 加了 TAB_QUERY_KEYS 与 Tabs items，漏了上面两处，
于是 changeTab('risk-control') 在第一行 `if (!isWorkerPlatformTab(nextTab)) return` 就返回了。

这类漏改没有任何报错信号，只能靠点一下才发现——上一轮的验证只查了构建产物里
是否含面板代码，没有验证 tab 真的能切换，所以没拦住。

## 修法

把名单抽到 utils/admin-worker-platform-tabs.ts，只保留唯一一份
WORKER_PLATFORM_TAB_KEYS；查询缓存映射与「只登记缓存但不是 tab」的例外（hall-config，
它是「杂项配置」tab 内部的区块）也一并显式化，避免下次再靠人记。

## 回归测试

新增 tests/admin-worker-platform-tabs.test.ts（5 个用例）：
  - 风控 tab 必须被 isWorkerPlatformTab 接受
  - 每个登记了切页缓存的 tab 都必须在合法 tab 名单里 ← 正是本次漏改的形态
  - 名单无重复项 / 非法 key 被拒 / 名单内自洽
