So that consumers of the events API can tell whether a sighting came
from the ARP scanner or the mDNS listener. Adds a DeviceEventScanner
enum (Arp / Mdns) plumbed from each scanner's call site through to a
new scanner column on device_events, exposed via the existing events
endpoint and OpenAPI schema. Pre-existing rows are backfilled with
'ARP' since that was the only scanner before mDNS.

The device event history chart previously fetched all events and filtered
client-side. This wires the existing created_from API parameter to the
frontend so filtering happens in the backend.
Also fixes a bug where the Today filter returned no results: rusqlite was
storing datetimes with a space separator ("YYYY-MM-DD HH:MM:SS+00:00")
while SQL filters used RFC 3339 with a T separator, causing string
comparisons to fail for same-day events. All datetime storage across
device_events, devices, and notifications is now consistently RFC 3339.
A migration converts existing records.

Records a DeviceEvent row on every scan: NewDevice when a device is first
seen, DeviceSeen on subsequent scans. Exposes GET /api/devices/{mac}/events
with pagination, ordered by date descending.
