fix(deploy): disable Gradio SSR + pin gradio==6.14.0 (HF Space stability) (#15)

The HF Space returned 503 (app healthy on :7860 but unreachable via HF's
proxy) because of Gradio's experimental Node SSR layer. Disabling SSR and
pinning gradio to match the README sdk_version restores stable serving
(verified 12/12 200s). Mirrors the fix already live on the deploy lineage.
