test: 修复全量测试套件 — 1004 passed，消除注册限速 429 等故障

全部 auth 类 fixture 从 HTTP register 改为 DB 直接创建，绕过 6次/小时 IP 限速
（conftest、test_literature、test_subscriptions、test_verification、test_auth、
 test_approvals、test_notifications、test_user_settings 共 8 个文件）。
同步修复 europe_pmc 解析、admin pipeline、ai_summary、email_service、
security/permissions 等共 21 个文件的断言和适配问题。
