fix: scaled width and height on recording

[aaronhallaert]

Issue

when 2 monitors are connected and one of them is scaled (e.g. 1.5), recording button doesn't do anything

Failed to detect output based on geometry (is your geometry overlapping outputs?)

This would work with slurp -o -d

Solution

make sure geometry is identical to slurp implementation by extracting scale from hyprctl monitors

• depends on bc
