chore: update supported models to latest versions (#1479)

## Summary
- **OpenAI**: Add gpt-4.1 family, gpt-4o-mini, o3, o3-mini
- **Anthropic**: Add claude-opus-4-6, claude-sonnet-4-6,
claude-haiku-4-5
- **AzureOpenAI**: Add gpt-5 family
- **Ollama**: Add llama3.3, llama3.1, qwen2.5-coder, deepseek-r1; keep
FunctionCalling false for all Ollama models due to inconsistent tool-use
support across quantizations

All existing model IDs are preserved for backward compatibility.

Closes #1419

## Test plan
- [ ] Verify the `/api/models` endpoint returns the updated model list
- [ ] Confirm UI model dropdowns display the new models correctly
- [ ] Verify existing model configs using older model IDs still work
