/**
 * A tour's packing link (P2D-XD-01), through the real JwtAuthGuard, AddonGuard
 * and TripAccessGuard against a migrated and seeded temp SQLite db, every
 * answer checked against its response contract. The permission check is a
 * container spy and the broadcasts go to a FakeRealtimeService.
 *
 * Fixtures: user 1 owns trip 5 and its packing list, user 2 is a member of
 * trip 5 whom the spy denies 'place_edit' and who keeps one item to
 * themselves, user 3 has no access to the trip.
