I think I found the answer in USB HID Usage Tables 1.5: https://usb.org/sites/default/files/hut1_5.pdf I think 10081 and 10082 correspond to 81 and 82 (System Power Down and System Sleep) in Generic Desktop Page (0x01).

The ones beginning with 7 correspond to values in Keyboard/Keypad Page (0x07), right?

Yes that is correct, however I have no idea why they are being sent simultaneous to the expected key codes. It could be a firmware bug, or maybe they trap the keycodes in their software and decided what keycode to pass to the host os depending on software settings. My main objective was just to get the keyboard functional under Linux.
