Add Precision Nudge Controls (Like in Satisfactory)

I think Enshrouded really needs a more precise building system, especially for walls, floors, roofs, and building blocks, not just regular objects.

Right now, building can get pretty frustrating when you’re trying to line things up perfectly or adjust small details. The “Y” undo helps, but it doesn’t actually solve the problem, it just feels like a band-aid.

In Satisfactory, there’s a really good system for this:
- You can press “H” to lock a hologram in place
- Then use the Arrow Keys to move it
- Use Ctrl + Arrow Keys for smaller adjustments
- Page Up/Down lets you adjust vertically

Something like that would make building way smoother and much less frustrating, especially for more detailed builds.
