Displays the RESOLVED provider identity - composing ProviderFallbackBadge for the tier and name - alongside the model id that actually served the request. While providerName is null it shows a Resolving provider placeholder, so the badge never claims a provider before one has resolved. Takes generic display props (providerName / tier / modelId / note). Distinct from ProviderFallbackBadge (the tier chip it composes): this adds the resolved provider identity plus the served model id. Data source: a provider-fallback resolver.
