Deleting a target soft deletes its row while its deliveries survive
in the per-webhook database, so the event log kept rendering the
history and lost the label: every historical row read ": delivered"
and the deliveries block was headed by an empty name.
loadTargetMap already loaded soft-deleted rows Unscoped for the
redactor half, then discarded them before building the view half.
It now builds both halves from every loaded row, and TargetView
carries a Deleted flag with a DisplayName that renders
"name (deleted)" — an operator debugging an old delivery needs to
know the target is gone, not just what it was called.
The views still come from NewTargetViews, so a deleted target's
configuration is masked by exactly the code that masks a live
one's. The widening is confined to this map, which feeds only
DeliveryView.Target on the event log page: the source detail
target list, the target edit form, the receiver and resubmit fan-out
and the delivery engine each resolve targets through their own
scoped queries, and the replay path keeps refusing a deleted target.
