An event with no consumer, published for the last time

An event dispatched on every order since 2021, subscribed to by a module that no longer exists.

$ ./bin/event-consumers --all | awk '$2==0'
  order.entitlements_recalculated   412,884

# 412,884 in 90 days, each one a serialisation, a
# broker round trip and an outbox row.

# and the check, monthly since 2024, which reported
# this correctly for eighteen months and was read once.

The monthly report had been correct since the module was discontinued and nobody had acted on it, which is the ordinary fate of a report that requires somebody to read it and decide. It is now a failing check rather than a report — an event with no consumers fails the build.
