Resolve the remaining lint warnings without changing behavior by fixing hook dependency lists, removing the icon naming false positive, and switching the YouTube thumbnail to next/image for compliant rendering.
Align the next-intl message schema across components, hooks, and locale files so the frontend uses one canonical structure instead of compile-first workarounds. Restore Spanish, French, German, Japanese, and Korean translations to the new schema while narrowing clipboard hook dependencies to translation contracts.
