/**
 * Tours e2e for city walks (CW-01 to CW-03, CW-10, CW-11, CW-13): a walk saved and read
 * with its stations, one saved with its stations only waiting for its way, the
 * keys of its stations kept through an edit, and the stations checked off on
 * the days the walk is on, and what is left of it read over MCP, 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.e2e.test.ts.
 *
 * Fixtures: user 1 owns trips 5 and 6, user 2 is a member of trip 5 whom the
 * permission spy denies 'place_edit' and 'day_edit', user 3 has no access to
 * either trip. Trip 5 has days 3 and 4, trip 6 has day 7.
