fix: simplify empty-state model selector

Keep the provider empty state focused on the setup action users need there:

choosing a model.

The refresh control, cache timestamp, and refresh explanation made the dialog feel

like a cache-management surface.

That extra action is out of place in the empty state, where the goal is to start

a chat with the selected provider and model.

Remove the refresh-specific UI from ProviderSelectionEmptyState and drop the

now-unused refresh/cache props from the ChatMessagesPane pass-through.

Refresh behavior remains available in the dedicated command result flow.
