/**
 * Tours module e2e: every /api/trips/:tripId/tours endpoint through the real
 * JwtAuthGuard, AddonGuard and TripAccessGuard against a real migrated and
 * seeded temp SQLite db (createSnapshotTestDb()). ToursService, PlacesService,
 * AssignmentsService and TripsService run their real SQL; only the permission
 * check (a container spy), the journey hooks and the WebSocket broadcast are
 * stubbed.
 *
 * Fixtures: user 1 owns trips 5 and 6, user 2 is a member of trip 5 whom the
 * permission spy denies 'place_edit', user 3 has no access to either trip.
 * AssignmentsModule and TripsModule are mounted next to ToursModule so the
 * one-tour-per-day 409 on move and the trip copy run through their real routes.
