The floating ai-chat.tsx was not sending the user's language to the /api/chat endpoint, causing it to always use the English system prompt. Now passes `language` from useLanguage() hook. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
Replaced ~100+ hardcoded French and English text strings across 30+ components with proper i18n t() calls. Added 57 new translation keys to all 15 locale files (ar, de, en, es, fa, fr, hi, it, ja, ko, nl, pl, pt, ru, zh). Key changes: - contextual-ai-chat.tsx: 30 French strings → t() (actions, toasts, labels, placeholders) - ai-chat.tsx: 15 French/English strings → t() (header, tabs, welcome, insights, history) - note-inline-editor.tsx: 20 French fallbacks removed (toolbar, save status, checklist) - lab-skeleton.tsx: French loading text → t() - admin-header.tsx, header.tsx, editor-connections-section.tsx: French fallbacks removed - New AI chat component, agent cards, sidebar, settings panel i18n cleanup Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
