Fix 404 errors: Add missing endpoints and chart page

- Add /api/models/reinitialize endpoint (alias for reinit-all)
- Add /api/sentiment/asset/{symbol} endpoint
- Add /api/news endpoint (alias for news/latest)
- Create chart page at /static/pages/chart/
- Fix system-monitor CSS/JS paths to use relative paths
- All endpoints return proper JSON responses
