fix(tui): show the actual subscription provider in the Go TUI

The Go TUI rewrite hardcoded "ChatGPT subscription" in the stats view and its
snapshot only carried a boolean, so a Grok run was labeled ChatGPT — the same
bug previously fixed on the Python side. Carry the provider label through the
snapshot protocol and render it, falling back to a generic "Subscription".

utils._subscription_label becomes public subscription_label since the TUI
backend now needs it too.
