feat(models): expose user BYOK availability

[chrarnoldus]

Summary

• Add optional hasUserByokAvailable metadata beside mayTrainOnYourPrompts in model catalog responses.
• Report whether each standard model has a compatible enabled personal or organization BYOK provider for authenticated requests.
• Mark direct BYOK models as available by construction while omitting the field for unauthenticated requests, experiment models, and custom LLMs.

Verification

Not manually tested; this is an API response metadata change with no visual surface.

Reviewer Notes

Kilo-exclusive models explicitly return false because their routing intentionally bypasses Vercel BYOK. Focused automated testing requires the repository test database, which is unavailable in this environment.
