The user plugin registered a cron dispatching to user:daily_audit, a task
pattern it never registers, and no audit logic exists anywhere in the plugin.
The daily run therefore went nowhere while a test asserted the schedule was
registered — proving the wiring existed, not that it worked. Implementing a
real daily audit is unstarted functionality, so the schedule is removed rather
than stubbed.
The combined domain test now asserts the real invariant across all applied
plugins: every schedule's task type must have a registered handler.
message_gateway scheduled message_gateway:cleanup_pairing_codes every 10
minutes but never registered a task under that pattern, so every dispatch
went to a task type with no handler and expired pairing rows accumulated
forever, even though repository.DeleteExpiredPairingCodes already existed.
Add a test that fails for any schedule whose task pattern is unregistered:
it reports the exact orphan rather than relying on a schedule-exists assert.
