Preserve SpaceNavigator detection from #7544

PR #7544 added the plain SpaceNavigator to the SE(3) product-string allowlist while
this branch was open. Carry that support over to the id-based matching and add the
device's USB identifier, which the author verified against hardware (046d:c626), so
the SpaceNavigator is also found when the HID backend cannot read its product string.
