Background revalidate provider models when model selector opens

On fresh startup the initial provider snapshot request can return
before providers finish loading, leaving the model picker empty.
The server broadcasts updates once providers are ready, but if the
user opens the picker in the interim they see "No models match".

Invalidate the React Query cache (background refetch, no loading
flash) every time the model selector popup opens so stale data is
silently refreshed.
