feat(models): add qwen/qwen3.7-plus to nous + openrouter catalogs (#39409)

Adds qwen/qwen3.7-plus directly under qwen/qwen3.7-max in both the
OpenRouter curated catalog (OPENROUTER_MODELS) and the Nous portal
catalog (_PROVIDER_MODELS['nous']), then regenerates the docs-hosted
model-catalog.json manifest from those source lists.
