feat: 重构测试框架 — 覆盖 6 端 (管理端 + 小程序 + 4 个移动端)

目录结构:
  tests/web/admin/       管理端 (Playwright)
  tests/web/mini_program/ 司机端小程序 (Playwright/微信 WebView)
  tests/app/driver_android/  司机安卓 (Appium)
  tests/app/shipper_android/ 货主安卓 (Appium)
  tests/app/driver_ios/      司机苹果 (Appium)
  tests/app/shipper_ios/     货主苹果 (Appium)

公共模块:
  tests/app/_shared.py       driver+ensure_logged_in 工厂
  tests/app/_base_page.py    App Page Object 基类

配置:
  test_config.yaml 拆分为 6 个独立 section + 货主账号
