PDA Power Monitor Clarity Upgrade

Depends on #6248, so if you're going to merge this, you'll want to merge that first.

In any case, this simply makes the PDA show where the power monitor is that you're looking at. This reduces ambiguity when you have multiple power monitors by the same name, such as if the players have made multiple consoles in game or prior to #6246, the two monitor computers in engineering as shown in the screenshot below)
