feat(plugin): 集成 WASM 插件系统到主服务并修复链路问题

- 新增 erp-plugin crate：插件管理、WASM 运行时、动态表、数据 CRUD
- 新增前端插件管理页面（PluginAdmin/PluginCRUDPage）和 API 层
- 新增插件数据迁移（plugins/plugin_entities/plugin_event_subscriptions）
- 新增权限补充迁移（为已有租户补充 plugin.admin/plugin.list 权限）
- 修复 PluginAdmin 页面 InstallOutlined 图标不存在的崩溃问题
- 修复 settings 唯一索引迁移顺序错误（先去重再建索引）
- 更新 wiki 和 CLAUDE.md 反映插件系统集成状态
- 新增 dev.ps1 一键启动脚本
