Opt-in to_dict over __table__.columns: auto-isoformat datetimes,
*_encrypted always dropped, __serialize_exclude__ for redacted columns,
serialize_extra() for computed fields (named to dodge ServerMetrics'
literal 'extra' column). 20 purely-mechanical to_dicts across 15 files
convert; genuinely custom shapes keep their hand-written methods (plan
75 §F's ruling stands). Field selection stays api/_query.py's job.
Gate: key-for-key parity against the pre-conversion key sets frozen
from git HEAD (only the Timestamp pair may be additive).

- ImageUpdateCheck model + ImageUpdateService: compare an app's local
RepoDigest against the registry's current index digest (via
`docker buildx imagetools inspect`) for the same tag, and flag
update_available when they differ. Shells out to docker like the rest of
the Docker layer; degrades gracefully when the image is local-only or the
registry is unreachable.
- API: admin POST /api/v1/image-updates/applications/<id>/check and
GET /api/v1/image-updates/applications/<id> for the latest result.
- Application.to_dict gains a lightweight image_update badge (mirrors the
existing image_scan badge).
- 7 tests: digest diff/match/unknown, no-image, badge, endpoint, auth gate.
