[BUG] --ls-vlan and quads-web vlans display incorrect values

[sadsfae]

It appears we may not be reclaiming vlan associations cosmetically, but functionally everything works.

quads --define-cloud --cloud cloud48 --description "RHEL Perf EL7 vs EL10" --cloud-owner yinsong --cloud-ticket 3976 - vlan 605

This applies and provisions:

-=>>python /usr/lib/python3.12/site-packages/quads/tools/ls_switch_conf.py --cloud cloud48
INFO - Cloud qinq: 0
INFO - Interface em1 appears to be a member of VLAN 1570
INFO - Interface em2 appears to be a member of VLAN 1571
INFO - Interface em3 appears to be a member of VLAN 1572
INFO - Interface em4 appears to be a member of VLAN 1573
INFO - Interface em5 appears to be a member of VLAN 605

However vlan associations page via quads-web lists it empty

QUADS CLI lists the old tenant that had this vlan:

-=>>quads --ls-vlan | grep 605
605: cloud06

This tenant cloud doesn't actually exist anymore.
