feat(pm/minion): support conference room monitor

I have my work dock monitors here, but that's not the only place I dock
my laptop at work: there's also a monitor in our conference room. The
auto layout places it at [0, 0] (due to the laptop monitor needing to be
placed further out so there aren't issues with xwayland...). Therefore,
I need to set it up manually or I will not be able to move windows to it
or otherwise use it.
