fix(models): exclude reseller providers from model catalog pages

Reseller providers like OpenRouter, Fireworks, Azure, Vertex, and Bedrock
are aggregators that proxy other providers' models. Their model detail
pages were generating broken links. Filter them out of
MODEL_PROVIDERS_WITH_CATALOGS so they don't generate static pages or
appear as clickable entries in the model directory.
