test(qa): e2e 装配修正 + 集成/门禁测试与工具链重构
- e2e：修死选择器与蜜罐误命中、补断言、GA4/security-headers 用例诚实标注 skip 边界；新增 assert-helpers/fixtures/hydrated/primary-nav/touch-targets 等复用桩。 - 集成层：config/test/jest.integration.config.js + tests-integration/ 真库 一次性 SQLite 用例，teardown 守卫开发库指纹。 - 门禁工具链：jest.setup 归位到根、scripts/accessibility 全站 axe 节点计数、 check-brand-text-token/check-motion-constraints 机械守卫、stryker/lighthouse 配置收敛。
