fix(proxy): revalidate proxy view when expanding a group

Badge values for freshly expanded rows seed from the cached proxy
view. Results that reach the core without a frontend event (tray
group test, provider health checks) are absent from that snapshot
until the next poll, so measured delays only appeared after another
interaction such as switching nodes forced a refetch. Route head
state patches through a wrapper that revalidates the view on
open transitions, matching how the group test already refreshes.
