FNXC:ModelCatalog 2026-07-08-00:00:
FN-7710 regression coverage: every CLI provider card's `onToggled` callback must refresh the
shared model catalog (`refreshModelsCache()`) in addition to the Settings Authentication panel
(`loadAuthStatus()`), so newly-enabled/disabled grok-cli/cursor-cli (and, for parity,
claude-cli/llama-cpp) rows propagate to every live picker without a Settings navigation.
This asserts the AuthenticationSection wiring only — the underlying refreshModelsCache()
single-flight/notify semantics are covered in useModelsCache.test.ts.
