fix(catalog): mark coreweave discovery authoritative

CoreWeave Serverless Inference (W&B Inference) is a reseller with a
rotating model menu, but its catalog entry omitted
dynamicModelsAuthoritative. Runtime /v1/models discovery therefore
merged into the frozen bundled slice instead of replacing it, so stale
ids (e.g. moonshotai/Kimi-K3, Kimi-K2.5) stayed selectable and 404 at
request time. Matches sibling resellers (baseten, gmi-cloud, aiand,
bedrock-mantle). Bundled models remain the offline/failure fallback via
the authoritativeFreshProviders gating in ModelRegistry.
