Drop the lease write's findings, the controller's artifacts-gone and the issuing gate (issue 1126, B9)

ADR 0590 supersedes the lease write: mesh-grants says no lease event any
more, so the watchman's lease-altered and removal-failed findings and
their row had nothing to hear. The ended controller's consumers are
removed as hand acts, so their deletion is no consumer lost; only the
one on DEAD_LETTER_NOTICES is still read, since its removal hands the
notices to the watchman. The builder hears artifacts-gone from the
artifact sweep seat alone, and mesh-enrolment's tokens no longer report
an issuing gate that nothing can turn off.
