/**
 * Tours e2e for runs (RUN-01, RUN-02): a run saved with its profile and pace, listed
 * and opened so, its time the distance at the pace, its pace changed or taken
 * out without touching the route or the days, refused without a profile or
 * with a pace out of bounds, copied, exported and imported, through the real
 * JwtAuthGuard, AddonGuard and TripAccessGuard against a migrated and seeded
 * temp SQLite db. The permission check is a container spy and the broadcast
 * goes to a FakeRealtimeService, as in tours-ski.e2e.test.ts.
 *
 * Fixtures: user 1 owns trip 5, user 2 is a member of trip 5 whom the
 * permission spy denies 'place_edit'.
