加桥/定位边界诊断日志，排查子游戏收不到 getlocationinfo

现象：大厅 H5 能正确拿到定位，子游戏拿不到。已静态排除「子游戏未注册
handler」与「回调错发给大厅」两个猜测（BridgeBus 是 per-WebView 实例、
handlers 是实例状态，反向 call 捕获各自的 bridge，物理上不可能串台；
下载真实子游戏 zip 比对后确认 H5 侧大厅/子游戏逻辑完全对称）。

为定位真正的失败层，在各组件边界加日志（纯诊断，不改任何行为）：
- BridgeBus 加 label（lobby / subGame）区分来源，记录 ← H5 调用、
  → H5 反向 call、native handler 未注册、evaluateJavaScript 失败
- sendToJS 改为返回 'ok'/'no-bridge'，H5 侧 bridge 未就绪导致的静默丢包
  现在会打错误日志（原实现 `if (window.X)` 直接丢弃，完全不可见）
- LocationService 记录 requestOnce 序号 / shared manager id /
  requestLocation 的 BOOL 返回值 / completionBlock 是否回来 / stop() 调用
  —— 高德文档明确 requestLocation 返回 NO 时 completionBlock 永不调用，
  当前代码忽略该返回值会让 continuation 永挂，H5 连 errorCode 12 都收不到
- H5ErrorRelay 补 console.warn 中继，让 WVJB「H5 侧无对应 handler」的
  warn 能出现在 Xcode console

契约影响：无。仅新增日志与可选 label 参数，桥接接口名 / 字段名 / 数据结构
均未变动（docs/H5-Native-Contract.md §3.1［20］/ §3.2［6］不变）。
