rename debug nightvision trait for clarity and improve some other debug trait descriptions

[NetSysFire]

Summary

None

Purpose of change

Did you know that you do not have to manually reveal overmaps and can just use the debug night vision trait for that? No? Well, now you do.
This improves some descriptions. Also do note that if you are using the graphical overmap, you are affected by #58904 and it will still look unrevealed to you.

Describe the solution

1. Rename the debug night vision trait to "Debug Night and Map Vision". Not 100% happy with the name, I considered renaming to "Debug Scout" but that is also not good. It is an improvement however.
2. Elaborate on a couple of confusing debug traits.
3. Add terminal punctuation on two unrelated debug traits.
