// TestAddClientTraffic_MatchesDespiteStaleInboundId reproduces the production bug where
// client_traffics rows survive an inbound delete+recreate with a stale inbound_id (the
// shared-by-email row keeps the deleted inbound's id, and AddClientStat's OnConflict-
// DoNothing never refreshes it). The old `inbound_id IN (local inbounds)` filter dropped
// those rows, so local traffic and online status stopped updating. The fix matches by
// email and only excludes rows owned by a node inbound, so a stale local row is still
// updated while a genuine node-owned row is left untouched.
