Disable scrollbars in VZ window

The scrollbars interfere with window sizing and cause content to be cut off,
especially on HiDPI displays and newer macOS versions (26.x). The NSScrollView
is still needed for magnification/zoom support, but the scrollbars themselves
are not necessary for normal operation.

Changes:
- Set hasVerticalScroller = NO
- Set hasHorizontalScroller = NO
- Set autohidesScrollers = YES (for any edge cases)

This fixes the issue where the VZ window shows scrollbars that cut off
approximately 16px of content in each direction.
