fix: update converter for current Gradio and Hub APIs

Upgrade the Space to Gradio 6.27.0 on Python 3.13 and migrate the Interface, queue and launch arguments. Preserve conversion concurrency 1 and queue size 10. Use CommitInfo.pr_url for the conversion result.

Validated with Python 3.13.13, a real local Gradio server, synthetic checkpoint loading and stubbed Hub uploads.
