[macos] `loginwindow` reported with latest macOS update

I'm running into an issue where `login window` is reporting > 1hr of usage over a week period. I think this issue is connected to AFK and how it works.

1. Does `Exclude AFK time` filter out time where there is no AFK data? i.e. will the login window time above be excluded?
2. If not, do you think we should just explicitly filter out loginwindow events (string matching on the title)? Or should we improve AFK to 'fill in' the missing time period when the computer was sleeping (similar to what the macOS window watcher implementation does).
