Introduce the Finding, FindingAudit, FindingKind, FindingStatus,
FindingPriority, FindingFilter, and FindingOrderField types in the
coredata layer. Add CRUD operations, list with filtering/pagination,
and audit association queries.
Remove the now-replaced nonconformity and continual_improvement
coredata types. Update entity type registry and snapshot types
to reference the new findings type.
