fix: simplify zoom to prevent empty space issues

The viewport-centered zoom approach was creating empty space above
the content when zooming to 50%, causing the CV to move down.

Solution: Simple top-anchored zoom
- Removed all complex scroll compensation logic
- Set transform-origin to "top center" (fixed position)
- Page now scales naturally from the top without movement
- No dynamic transform-origin calculations
- No scroll position adjustments

Result:
- Page stays anchored at top during zoom
- No empty space created above content
- Clean, predictable zoom behavior
- Works correctly at all zoom levels (50%-200%)

The page simply scales up/down from the top center point,
maintaining its position without any jumping or space issues.
