Fix docks disappearing in NAV when >100% UI scale (#2898)

* Fix docks disappearing in NAV when >100% UI scale

The occlusion bounds in the dock drawing code didn't take into account
UI scale, so docks passed a certain point would disappear.

Fixes #2775

* Update Content.Client/Shuttles/UI/ShuttleNavControl.xaml.cs
