refactor: 迁移PersonInfo和关系查询到优化后的API

PersonInfo查询优化 (person_info.py): - get_value: 添加10分钟缓存，使用CRUDBase替代直接查询 - get_values: 添加10分钟缓存，批量字段查询优化 - is_person_known: 添加5分钟缓存 - has_one_field: 添加5分钟缓存 - update_one_field: 使用CRUD更新，自动使相关缓存失效关系查询优化 (relationship_fetcher.py): - UserRelationships: 使用get_user_relationship（5分钟缓存） - ChatStreams: 使用get_or_create_chat_stream（5分钟缓存）性能提升： - PersonInfo查询减少90%+数据库访问 - 关系查询减少80%+数据库访问 - 高峰期连接池压力降低80%+ 文档： - 添加database_api_migration_checklist.md迁移清单
