The toolset config panel highlighted the first keyless provider (e.g.
Nous Portal) on load instead of the provider actually written to config.
The /api/tools/toolsets/{name}/config endpoint never reported which
provider was active, so the GUI's default-expand logic fell back to
"first configured" — and keyless providers are always "configured".
Backend now annotates each provider with is_active (via the same
_is_provider_active helper the CLI 'hermes tools' picker uses) plus a
top-level active_provider summary. The panel prefers that signal before
falling back to first-configured/first.
Adds a frontend regression test (active provider is expanded on load)
and backend coverage (config reports is_active/active_provider; selecting
a provider round-trips into the next config read).
