fix(compose-doctor): resolve effective healthcheck coverage (#1713)

* fix(compose-doctor): resolve effective healthcheck coverage

Compose Doctor now classifies healthcheck coverage from the Compose model, running containers, and local images so image-provided HEALTHCHECKs are not false positives. Update Guard shares the same presence helper so test NONE is not treated as active.

* fix(compose-doctor): fix healthcheck project label and empty compose HC

Use the Compose project name for runtime container listing so stacks whose name: differs from the directory still get runtime evidence. Treat empty or timing-only healthcheck objects as absent rather than active.

* fix(compose-doctor): treat inherited healthcheck as All Clear note

Inherited image healthchecks no longer block All Clear; they surface under a notes section and cannot be acknowledged.
