/**
 * The nightly cleanup of the sign-in ledgers (`auth-ledger-cleanup`).
 *
 * A row goes once it has been expired for longer than its grace (30 days for
 * sessions, tokens and trusted devices, a day for challenges). A live row, a
 * recently expired one, a revoked token that has not expired, and a revoked
 * token without an expiry all stay. The delete is batched and says when it
 * stopped with rows left.
