ListEnabledCheckDefs now LEFT JOINs the target entity and excludes rows whose
target is deprecated or destroyed, so retired things (secrets-issuance,
homelab-mcp, the dead secrets ingress route) stop generating permanent false
alarms instead of waiting for an operator to disable the check_def by hand.
coverageSweep's None() branch previously did nothing, so a type changed from
declared monitoring to `monitoring: none` (dns-zone) left its open
`unmonitored` signals lingering forever — a None() entity never gains a check,
so the hasCheck resolution path never fired. It now resolves those signals.
