[Chore/Refactor] Native Support for Dataclasses Mapped as ORM Models

continue #23579

since that issue is too long, and most orm model has been migrated.

@dosu tell me current status.

Start by reading issue #23579, which this issue continues, and review its current migration status for ORM models. Identify which dataclass-based models remain and confirm the expected native ORM support before making changes. Done means the remaining migration work is complete and the affected models continue to function as ORM models.
