fix(udev): restrict mode switching to intended devices and events

Browse Source 
Take the aic.rules portion of #129: restrict 1111:1111 switching to
88M80 USB devices, target the event's bus/device address, and eject only
whole disks on add. Add selection fixtures and document the product
restriction. Keep installer paths and existing firmware handling unchanged.
