Three labels in the device summary sit a column off from the rest:
Protocol : HID++ 4.2
Report Rate : 1ms
Serial number: 6FF83E8B
Model ID: 4099C0950000
Unit ID: 6FF83E8B
Neither offset looks deliberate. "Report Rate" arrived in a6f7507c as a
rename of "Polling rate", one character shorter, and kept the old single
trailing space, so its label is 12 columns where every neighbour is 13.
"Model ID" and "Unit ID" arrived in b1d4b2f3 written as label, colon, then
padding, rather than the padded label then colon used above them; both
still land their values in the shared column, so the values were clearly
being aligned and the colon simply followed the other style.
Pad all three to the 13-column label the rest of the block uses, so the
colons line up with the values that already did.
Battery, Notifications and Features are left alone -- those read as
sentences rather than as entries in this column.
