Vat Track Responsive Improvements

[brian-mckeown]

Vat Track Reaponsiveness in EFB app could be better. Large border gaps seen on larger widescreen monitors or monitors with high resolutions.

Also, top navbar needs to be frozen in place for vat track. Sometimes navbar disappears when zooming or scrilling the map, especially on mobile devices.
