feat(mobile): login, password change and logout screens

P3 Task 3 移动端(对接 Task 2 api client + 本任务新增的后端契约):

- 登录页实装:账号/密码表单(空值客户端校验)→ api.login(会话自动
  持久化)→ pushReplacement /home;错误码本地化(AUTH_INVALID_
  CREDENTIALS / AUTH_RATE_LIMITED(含稍后再试文案)/ 网络 / 校验);
  提交加载态防重复提交。
- 修改密码页(设置页入口):当前/新/确认三字段,客户端校验(≥8 位、
  两次一致)→ api.changePassword → toast + pop;成功后本地会话不变
  (服务端保留当前会话);旧密码错误(401 AUTH_INVALID_CREDENTIALS)
  显示「当前密码错误」且不触发 401 驱逐。
- 退出登录:设置页按钮 → api.logout 尽力而为 → 清会话 → 清栈回
  /login;App 壳 initState 注册 onUnauthorized(业务 401 → 清栈 /login),
  根 navigatorKey 接线;password-change 的 401 豁免会话驱逐(拦截器
  豁免集合与令牌附加分离)。
- l10n:新增 16 组 zh/en 文案;错误码 → 文案解析扩展
  (core/error_l10n.dart,errorCode→AppLocalizations)。
- 测试:ApiClient.changePassword 单测 ×2(Bearer+请求体;旧密码 401
  不驱逐);widget 测试 ×12(登录 5:空值/成功跳转/凭据错误/限速文案/
  加载禁用;改密 4:过短/不一致/旧密码错误文案+会话保留/成功 toast+pop
  且令牌不变;设置 2:改密入口跳转/登出清会话回登录;App 壳 1:401
  清栈回 /login)。flutter analyze 0 issue;flutter test 81/81。
