feat(cross_end): add cross-platform E2E test support for freight full flow

Add tests/cross_end/ directory with dual-driver architecture:
- conftest.py: Playwright admin_page + Appium app_driver fixtures
- Admin Page Objects: FreightSourcePage, WaybillManagementPage, SettlementPage
- App Page Objects: DriverOrderListPage, DriverTransportPage, DriverHomePage (re-export)
- test_freight_full_flow.py: 8-step end-to-end test (publish → accept → load → unload → accounting → review → shipper pay → platform pay)
- Shared context dict for cross-step data passing
- Graceful skip when either Playwright or Appium is unavailable
- All selectors marked with ⚠️ placeholders for discovery against real environments

Add cross_end marker to pytest.ini for selective execution.
