Subject: [PATCH] feat(i18n): Add internationalization support

- Add i18n module with locale loading and translation helpers
- Add English (en) and French (fr) locale files with comprehensive translations
- Inject locale data into dashboard HTML via server
- Add /api/locales endpoint for locale info
- Add t() translation function to dashboard

Translated elements:
- Boot sequence (initialization, connecting, sweep complete)
- Header pills (sweep, sources, delta, risk indicators)
- Left rail panels (sensor grid, nuclear watch, risk gauges, space watch)
- Layer names and descriptions
- Map legend items
- Lower panels (news ticker, sweep delta, macro+markets, trade ideas)
- Right rail (OSINT stream)
- Badges and status indicators

Supported languages: English (default), French
Set CRUCIX_LANG=fr to switch to French
