Major rewrite of reconstruction rendering:
- Page split into vertical sections (content/box) around box boundaries
- Content sections: uniform row height = (last_row - first_row) / (n-1)
- Box sections: rows evenly distributed within box height
- Content rows positioned absolutely at original y-coordinates
- Font size derived from row height (55% of row height)
- Multi-line cells (bullets) get expanded height with indentation
- Boxes render at exact bbox position with colored border
- Preparation for unified grid where boxes become part of main grid

Replace manual word_box positioning (wild/unsnapped) with the
server-rendered words-overlay image from the OCR step endpoint.
This shows the same cleanly snapped red letters as the OCR step.
Endpoint: /sessions/{id}/image/words-overlay

- Font: use font_size_suggestion_px * scale directly (removed 0.85 factor)
- Row height: calculate from row-to-row spacing (y_min of next row
minus y_min of current row) instead of text height (y_max - y_min).
This produces correct line spacing matching the original layout.
- Multi-line cells: height multiplied by line count
Content zone should now span from ~250 to ~2050 matching the original.

Left panel: Original scan + OCR word overlay (red text at exact
word_box positions) + coordinate grid
Right panel: Reconstructed layout + same coordinate grid
Features:
- Coordinate grid toggle with 50/100/200px spacing options
- Grid lines labeled with pixel coordinates in original image space
- Both panels share the same scale for direct visual comparison
- OCR overlay shows detected text in red mono font at original positions

New pipeline step showing the reconstructed page with all zones
positioned at their original coordinates:
- Content zones with vocabulary grid cells
- Box zones with colored borders (from structure detection)
- Colspan cells rendered across multiple columns
- Multi-line cells (bullets) with pre-wrap whitespace
- Toggle to overlay original scan image at 15% opacity
- Proportionally scaled to viewport width
- Pure CSS positioning (no canvas/Fabric.js)
Pipeline: 14 steps (0-13), Ground Truth moved to Step 13.
Added colspan field to GridEditorCell type.
