### LAZY loading for Relation.anchorPerson/.holderPerson/
The slowest query now was fetching Relations joined with Contact, Anchor-Person and Holder-Person, for all tables using the restricted (RBAC) views (_rv).
We changed these mappings from `EAGER` (default) to `LAZY` to `@ManyToOne(fetch = FetchType.LAZY)` and got this result:

## Summary
Now, finally, the total runtime of the import was down to 12 minutes.
That the import runtime is down to about 12min is repeatable, where originally, the import took about 25mins in most cases and just rarely - and for unknown reasons - just 10min.
Merging the recursive CTE query to determine the RBAC SELECT-permission, made it more clear which business-queries take the time.
Avoiding EAGER-loading where not neccessary, reduced the total runtime of the import to about the half.
