feat(web,plugin): P1 跨插件引用 — 前端 Phase 4

- plugins.ts: PluginFieldSchema 新增 ref_plugin/ref_fallback_label, PluginEntitySchema 新增 is_public
- pluginData.ts: 新增 resolveRefLabels/getPluginEntityRegistry API
- EntitySelect: 支持 refPlugin 跨插件查询，目标不可用时降级为禁用 Input
- PluginCRUDPage: 表格列解析引用标签（蓝色 Tag），entity_select 表单传 refPlugin/fallbackLabel
