Propagate AbortSignal to all provider fetchers and use native timeout

- Remove inline withTimeout helper in favor of AbortSignal.timeout()
- Add optional AbortSignal parameter to all provider model fetchers:
  - openrouter, requesty, glama, unbound, litellm, ollama, lmstudio
  - deepinfra, io-intelligence, vercel-ai-gateway, huggingface, roo
- Standardize timeout handling across modelCache and modelEndpointCache
- Add useRouterModelsAll hook for settings UI to fetch all providers
- Update Unbound and ApiOptions to use requestRouterModelsAll

This ensures consistent cancellation behavior and prepares for better
request lifecycle management across the codebase.
