This is more or less a variant of the problem libtaskmanager faces when trying to map WM_CLASS to .desktop files, so you can find some code there. We've (Ivan + me) struggled with this with KActivities too however and the best we came up with so far is the awful storageIdFromService() in Kicker's actionlist.cpp.

A downside of this is that (in the current implementation, anyways) in case you do not group your tasks and you have multiple windows of the same task open, it will show the same information on all entries.

The badges are only shown if 1) the cell is large enough 2) the label is *not* shown (ie. icon tasks manager or the regular one in very narrow). The badge is just a circle in theme highlight color, not an actual SVG - it cuts off part of the icon to provide more contrast. The "urgent" state just highlights the entry as if it requested attention, there's no wiggle animation and this is nowhere integrated with the window manager, also I did not find an application that used this, so I have no idea how it's used by them.

Thunderbird also registered a launcher on DBus but it never actually set a badge although I had unread mail. I copied a folder in Dolphin and got proper progress; also I played around with JobViewServer on DBus and it behaved correctly, even in case there were multiple progresses in one application.
