feat(inference-providers): graduate alibaba to user BYOK

[kilo-code-bot]

Summary

• Moves alibaba from VercelNonUserByokInferenceProviderIdSchema to VercelUserByokInferenceProviderIdSchema, exposing it as a user-BYOK provider via the Vercel AI Gateway.
• Adds Alibaba to the display-name map in BYOKKeysManager so it appears in the BYOK UI.
• Adds a UserByokTestModels entry using alibaba/qwen3-coder-plus as the default test model.
• Updates the qwen model-prefix mapping to reference the new user-BYOK enum location.

Verification

Verified locally that VercelUserByokInferenceProviderIdSchema.enum.alibaba type-checks in getVercelInferenceProviderConfigForUserByok and inferVercelFirstPartyInferenceProviderForModel.

Visual Changes

N/A

Reviewer Notes

The Alibaba default test model was selected from the Vercel gateway catalog; alibaba/qwen3-coder-plus is served by the alibaba upstream provider, making it a natural round-trip check for a user-supplied Alibaba API key.

Difference between Alibaba and Vercel handling of reasoning is a problem here (reasoning_content vs reasoning_details).
