feat(crm): 创建 CRM 插件 crate + 前端 tabs/tree 页面类型 + 动态菜单

- CRM WASM 插件：Cargo.toml + src/lib.rs + plugin.toml（5 实体 + 9 权限 + 6 页面）
- 注册 erp-plugin-crm 到 workspace members
- PluginTabsPage: 通用标签页容器，递归渲染子页面
- PluginTreePage: 通用树形页面，前端构建树结构
- App.tsx: 新增 /tabs/:pageLabel 和 /tree/:entityName 路由
- plugin store: 从 manifest pages 生成菜单（支持 tabs 聚合）
- MainLayout: 动态图标映射（team/user/message/tags/apartment）
