feat: Added ability to lock a tactical map object to screen

[mitchell-foote]

Description

Implemented the ability to lock an tactical map icon to the screen borders.

As a note, there was a duplicated file, as the logic needed to be shared across the server and the client, and the tsconfig wasn't playing nice with trying to reference files across that barrier. If needed I can go back and do some additional modifications to force that to work, but overall, it should be pretty straightforward.

Code changes include:

Adding some height and width fields, as well as a boolean field to signify that it should lock to screen.

Additional code changes are about checking that field, and making sure that the icon stays where it needs to.

I could have sworn there was a way to share logic between the server and the client. Alas.
