Subject: [PATCH] fix: backup LUKS rsync tolerance, stale mapping cleanup,
 tier-4-aux quota bump
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- daily-backup: handle rsync exit 23 (partial transfer) as OK for LUKS
  noload mounts — in-flight writes have corrupt metadata from skipped
  journal replay, but core data is intact
- daily-backup: clean up stale LUKS dm mappings from previous crashed
  runs before attempting to open
- daily-backup: capture rsync exit code safely with set -e (|| pattern)
- kyverno: bump tier-4-aux requests.memory 2Gi→3Gi (servarr was at 83%)
- actualbudget: patched custom quota 5Gi→6Gi (was at 82%)

Verified: backup now completes status=0 (96 PVCs OK, 0 failed)

[ci skip]
