feat(ai): Phase 3A RAG 知识库 — CRUD API + Agent Tool + 向量知识源 + 前端管理页

- 知识库 REST API: 10 个端点 (references/guides CRUD + re-embed)
- search_medical_knowledge Agent Tool: 语义检索参考资料和临床指南
- VectorKnowledgeSource: 实现 KnowledgeSource trait，自动降级
- 沙箱配置: Patient/MedicalStaff 允许使用知识库检索
- 前端 AiKnowledgePage: Tabs(参考资料/临床指南) + Table + Modal CRUD
- 权限码 seed 迁移: ai.knowledge.list + ai.knowledge.manage + 菜单
