fix: 修复主程序卡死与下载器集成，新增真实数据测试

- LookingWebMain: 强制 IPv4 避免 IPv6 不可达挂起；requests 加超时防卡死 - get_seed_from_element_detail: 修复限流页崩溃与 favicon 误作来源 URL，改用 canonical/传入 URL - QbittorrentDownloader: 修复 main() 中模块/类误用导致的 download_by_seed AttributeError；请求加超时 - MySqlService: 修复数据库不可达时 query/execute/close 的 None 崩溃，close 后置空 connection - 新增 cf_session: Cloudflare 人机认证 cookie 管理 + 限流退避重试 + 自动弹浏览器刷新验证 - 新增 refresh_cf_cookies.py: 弹出浏览器手动验证并保存 cf_clearance - tests/: 真实网络/数据库测试（get_page、seed_is_exist、cf_session）+ run_tests.py runner - 清理无用脚本(final_test2/verify_replace/REPLACEMENT_INFO)，.idea 与 cookie 文件入 .gitignore 注: test_qbittorrent_downloader.py 11 个用例为既有失败（mock 目标 session 为实例属性，与实现错配），未在本次范围
