fix(plugin): P1 跨插件引用修复 — DateTime generated column + resolve-labels UUID 类型 + EntitySelect manifest→UUID 映射

- manifest.rs: DateTime 类型 generated column 改为 TEXT 存储（PostgreSQL TIMESTAMPTZ cast 非 immutable）
- data_handler.rs: resolve-labels 查询参数从 String 改为 UUID 类型避免类型不匹配
- data_dto.rs: PublicEntityResp 新增 plugin_id 字段
- EntitySelect.tsx: 跨插件查询先通过 registry 解析 manifest_id→plugin UUID
- pluginData.ts: PublicEntity 接口增加 plugin_id
- plugin_tests.rs: 适配 PluginField/PluginEntity 新增字段
