feat(models): add deepseek/deepseek-v4-pro to OpenRouter + Nous Portal curated lists (#20495)

Endpoint re-tested over 6 conversational turns (9 API calls, 3 tool calls)
and an 8-request burst — no rate limits, no errors, ~2-3s latency. The
historical rate-limit issues that caused its removal are gone.

- hermes_cli/models.py: add to OPENROUTER_MODELS and _PROVIDER_MODELS['nous']
- website/static/api/model-catalog.json: regenerated via build_model_catalog.py
