## Summary
- Fix `syncApplication` crashing with `ENTITY_NOT_FOUND` when a
navigation menu item child (with `folderUniversalIdentifier`) appears
before its folder in the manifest's `navigationMenuItems` array
- Add a generic topological sort in
`WorkspaceEntityMigrationBuilderService.validateAndBuild()` that detects
self-referential FKs from `ALL_MANY_TO_ONE_METADATA_RELATIONS` and
ensures parents are created before children
- This also covers other self-referential entities:
`viewFilterGroup.parentViewFilterGroup`,
`fieldMetadata.relationTargetFieldMetadata`, and
`rowLevelPermissionPredicateGroup.parentRowLevelPermissionPredicateGroup`
## Root cause
The builder iterated `createdFlatEntityMaps.byUniversalIdentifier` in
insertion order (from the manifest). Validation passed because it
checked both optimistic maps and remaining-to-create maps. But the
runner processed create actions sequentially, so
`resolveUniversalRelationIdentifiersToIds` threw when the folder hadn't
been created yet.
