fix(router): match provider-prefixed fallback keys for bare model groups served by wildcard deployments (#43062)
* fix(router): match provider-prefixed fallback keys for bare model groups

* fix(router): infer the fallback key's provider the way routing does for bare model groups

A bare model group served by a wildcard deployment (claude-sonnet-4-6 routed to anthropic/*) now finds a fallback keyed <provider>/<group>. The provider is inferred through one shared helper, inferred_provider, which the pattern router already used inline, so the fallback lookup and routing agree on the prefix. The lookup only infers a provider when some fallback key ends in /<group>, so alias-style groups never hit the resolver

* fix(router): resolve context window and content policy fallback keys through the shared lookup
