fix(mobile): distinguish auth failure from HR mismatch on position sync page

问题:登录态失效(token 冻结/无效,后端返 401)时,同步岗位页把认证错误
误显示成「人力系统中未匹配到当前手机号的在职岗位,请联系 HR」,员工被
困在该页无路可退。

修复:
- api.ts: 新增 ApiError(statusCode/bizCode) 类型化错误与 isAuthApiError,
  readPayload/parsePayloadText/XHR 路径统一抛出带状态码的错误,消息不变
- position.ts: fetchOrgPositionResult 返回四态判别结果
  matched/unmatched/unauthorized/error;hydratePositionFromOrg 行为不变
- position/index.vue: 按四态分支处理——
  · unauthorized -> 清除登录态并自动回登录页(保留 redirect)
  · error -> 提示「网络异常…请重试」,保留重试按钮
  · unmatched -> 才显示联系 HR 文案
  并新增「退出重新登录」链接(确认弹窗后清登录态回登录页),
  避免任何异常场景下用户被困无退出路径

验证(构建产物 + 生产 API,Playwright 五场景全过,截图见
.data/visual-audit-20260718/position-fix/):
S1 固定码真实登录->今日页(保洁岗匹配) S2 无效token->自动回登录
S3 断网->网络异常提示留在本页 S4 有效token->自动通过
S5 退出链接->确认->回登录且登录态已清
