restore floating restart card, treat local providers as available

Bring back the floating restart notification card below the settings
modal (message only, no restart button). The card fades in on credential
changes and auto-dismisses when leaving the providers section.

Treat setupMethod: "local" providers (e.g. Ollama) as always available
when computing hasModelProvider, matching the Goose backend's
check_provider_configured behavior. This prevents local-only users from
seeing a perpetual needs_model indicator on the Goose agent card.
