fix: Correct background grid rendering at high zoom levels

Browse Source 
- Fix grid line coordinate transformation (world to screen)
- Properly align grid with zoom and pan transformations
- Calculate grid start position at GRID_SIZE multiples
- Draw grid lines across entire visible canvas area
- Ensure grid lines render completely regardless of zoom level
- Grid now displays consistently at all zoom magnifications

Fixes: Grid no longer disappears or renders incompletely when zoomed in
