Release 1.0.10 with subpath deployment and modal menu invokes.

Add app_base/router_base config, compat path helpers, and scoped service worker
registration so apps can mount under a URL prefix. Wire invoke_type modal through
a handler registry and open the notification center from the standard menu flow.
