feat(models): add Nebius model mappings

[RATCHAW]

Summary

• add Nebius mappings for current DeepSeek, MiniMax, Kimi, Hermes, Nemotron, Cosmos, GLM, Gemma, and Qwen models
• add OpenBMB catalogue support with MiniCPM-V 4.5 and expose OpenBMB in the open-source family filter
• align existing Nebius pricing, context limits, capabilities, stability, and endpoint availability with live provider behavior
• resolve embedding base URLs through the shared provider configuration so Nebius-hosted embedding models use the correct endpoint

Why

The model catalogue did not reflect Nebius's current hosted lineup or several behaviors verified against its live endpoints. Embeddings also used a local base-URL allowlist, which omitted provider defaults already maintained by the shared actions package.

Impact

Nebius models can be selected and routed with accurate capability metadata, Qwen3 Embedding 8B can use the Nebius endpoint, and removed or unreliable deployments are kept out of normal routing.

Validation

• pnpm format
• pnpm build (17/17 tasks passed)
• pnpm test:unit (2,865 passed, 2 skipped; one unrelated timezone-sensitive calendar-month assertion failed under Africa/Casablanca)
• TZ=UTC pnpm exec vitest run packages/db/src/api-key-period-limit.spec.ts --no-file-parallelism (5/5 passed, confirming the unrelated failure is timezone-dependent)

Summary by CodeRabbit

• New Features
  • Added support for additional Nebius-hosted models, including OpenBMB, NVIDIA, Nous Research, Moonshot, Z.ai, DeepSeek, and Alibaba.
  • Added the Qwen3 Embedding 8B model for embedding requests.
  • Added OpenBMB models to the Open Source category filter.
• Updates
  • Expanded embedding model compatibility and improved embedding endpoint/provider selection.
  • Updated pricing, context limits, and capabilities for multiple existing models; marked some deployments as no longer available.

Walkthrough

The PR updates embedding upstream URL resolution and expands the model catalog with OpenBMB registration plus new or revised Nebius provider configurations across multiple model families.

Changes

Embedding routing

Layer / File(s)	Summary
Provider base-URL resolution apps/gateway/src/embeddings/embeddings.ts	The embeddings route uses getProviderDefaultBaseUrl(providerId) instead of an inline provider URL map and broadens the dimensions schema description.

Model catalog

Layer / File(s)	Summary
OpenBMB model registration packages/models/src/models/openbmb.ts, packages/models/src/models.ts, packages/shared/src/components/models-directory/model-category-filters.ts	Adds the minicpm-v-4.5 model, includes it in the consolidated registry, and classifies the openbmb family as open source.
Nebius model definitions packages/models/src/models/alibaba.ts, packages/models/src/models/deepseek.ts, packages/models/src/models/google.ts, packages/models/src/models/minimax.ts, packages/models/src/models/moonshot.ts, packages/models/src/models/nousresearch.ts, packages/models/src/models/nvidia.ts, packages/models/src/models/zai.ts	Adds Nebius-backed models and provider entries, deactivates unavailable endpoints, and updates pricing, context, quantization, and capability metadata.
