feat: payment SDK integration, attribution window config, E2E tests, CI integration, rules center tests

- WeChat Pay V3: real API calls with HMAC-SHA256 signing, AES-GCM callback decryption
- Alipay: real API calls with RSA2 signing, WAP payment support
- Both gateways fallback to MockGateway when unconfigured
- Attribution window configurable via ATTRIBUTION_WINDOW_DAYS env var (default 28)
- 30 platform-specific rule test cases (WeChat/Zhihu/Xiaohongshu/Baijiahao/Toutiao/Douyin)
- Fixed clickbait detection bug (character-level to word-level matching)
- E2E tests for diagnosis-strategy and content-monitoring flows
- CI: e2e-test job, bandit security scan, npm audit, performance baseline
