feat: configurator overhaul — full i18n, AI brief generation, redesigned UI

Configurator:
- Full i18n: industries, timelines, AI types, field labels, error messages,
  complete screen — all translated to French
- Real AI brief generation via OpenRouter (DeepSeek V3.2) with fallback template
- Fixed email notification bug (was sending to client instead of admin)
- Added wizard reset capability ("Start Over" button on success screen)
- Redesigned section shell with refined card, accent line, step indicators
- All step components use translation keys instead of hardcoded strings

Hero:
- Tighter spacing to keep CTAs above the fold
- Reduced bottom gradient height

Footer:
- Removed GitHub link
- Legal name in copyright
- "American-founded" location text
