fix(mcp-crud-ui): address greptile 3/5 review

- remove non-functional XIcon remove-server button (no onRemoveServer prop wired)
- fix stale closure in MCPAppsPanel auto-enable effect: use serversRef/selectedServersRef
- remove utility re-export from McpCrudPermissionPanel (classifyToolOp, groupToolsByCrud)
- remove redundant selectedTools.length === 0 guard (always true when !toolPermissions[id])
