Patch 6348 list rules keyerror

[voetberg]

Addressing issue #6348 and adding a test for it.
I missed the commit message format in the contrib guidelines first time around - so we have some duplicate commits from the rebase.

Welcome! I have impression that you misunderstood the issue. No changes are expected in the Rucio client. Instead, you should modify the core to include the missing information.

rucio/lib/rucio/core/rule.py

Lines 881 to 901 in 7bbdf63

Forgive me for neglecting this for so long.

Please try to mimic #5978 #6297: use this opportunity to make improvements to the existing code (SQLAlchemy 2.0 syntax), but as a separate commit. Refer to the discussion in that PR if curious for the justification.

We’ve had to give priority to the other PR. Now that it is merged, kindly amend your work over the latest master branch. Thank you in advance.

Marvelous. Many thanks and sorry about the long delay. @bari12 I propose to make a freeze exception.
