// TestAuthTokenBootstrapsLexicons verifies that a user who has never pushed
// or pulled — and therefore has no sailor profile in their PDS and no crew
// record in the hold's PDS — gets both written by the time their very first
// /auth/token call returns.
//
// The two writes happen on different code paths:
//   - sailor profile: post-auth callback runs storage.EnsureProfile against
//     the user's PDS (the fake testpds in this test).
//   - hold crew: authgate.Authorize runs storage.EnsureCrewMembership, which
//     mints a service-auth via the user's PDS and POSTs requestCrew to the
//     hold, which writes io.atcr.hold.crew into its embedded PDS.
//
// Both run during the same /auth/token request (the post-auth callback is
// synchronous and the authgate goroutine is awaited before the handler
// returns), so a 200 from /auth/token is the signal that both records exist.
