feat: CSS Grid editor with OCR-measured column widths and row heights

Backend: add layout_metrics (avg_row_height_px, font_size_suggestion_px) to build-grid response for faithful grid reconstruction. Frontend: rewrite GridTable from HTML <table> to CSS Grid layout. Column widths are now proportional to the OCR-measured x_min/x_max positions. Row heights use the average content row height from the scan. Column and row resize via drag handles (Excel-like). Font: add Noto Sans (supports IPA characters) via next/font/google. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
