fix(ux-audit): landing next/image + confirm AlertDialog + search-modal i18n

Landing page:
- <img> → next/image avec width/height (CLS fix)
- padding nav responsive px-4 sm:px-8

note-card:
- confirm() natif → AlertDialog (non-bloquant, stylable)
- showLeaveDialog state + dialog component

search-modal (20 chaînes FR → i18n):
- useLanguage ajouté
- 20 strings FR hardcoded → t('searchModal.*')
- Clés ajoutées dans en.json + fr.json
