Gate notification persistence and delivery on the device-event
deduplication window, not just the device_events table: record_event now
reports whether it recorded, and classify_new_device/classify_existing_device
suppress their changes when the sighting is a duplicate.
Treat an empty->value IP fill as not a change via a new ip_changed helper
(mirroring vendor_changed), so a device gaining its first address raises no
"changed" notification.
Key deduplication on (mac, scanner, event_type) instead of (mac, ip,
scanner), so repeated sightings of the same kind collapse regardless of the
reported address.
Also delete stale oott.db-wal/-shm in run_tests.sh to avoid init_db panics.

Purges records older than a configurable window (default 365d) once per day.
Also adds a composite index on device_events(mac_address, created_on DESC) for
efficient scan history queries at scale, and fixes a non-deterministic pagination
order by adding id as a tiebreaker to ORDER BY.

Add run.sh script to start the backend (erases db, runs cargo with sudo
using user's CARGO_HOME to avoid full recompilation). Remove sudo from
cargo test in run_tests.sh for the same reason.
