Active scanners (ARP, SNMP) now accumulate every change across a whole
scan and emit one notification per type via events::notify: a single
device produces the usual single-device notification (carrying its MAC),
while two or more produce one consolidated summary with an empty
mac_address. Device events are still recorded per device.
Notification bodies no longer include MAC or IP addresses; the title
MAC fallback is masked to the last two octets. Summaries list up to
three devices then "…and N more devices".
Split sighting handling so record_sighting persists + records the event
and returns Vec<DeviceChange>; passive listeners (mDNS, SSDP, DHCP) use
record_and_notify since they see one device per event.
Also fixes NotificationType::from_str never mapping "DeviceChanged",
which made those notifications round-trip from the DB as Other.
Frontend: the card already hides the device link when mac_address is
null; added widget tests for the present/absent link cases.

Tapping a notification's body already toggled expand/collapse, but the
action area below it wasn't tappable. Wrap the whole card in an InkWell
so tapping anywhere (body or action row) toggles, while the buttons
still handle their own taps.
