Subject: [PATCH] Fix: Use PAPERLESS_REDIS_PREFIX for Celery result backend
 keys (#14015)

PR #12741 sets the result backend for Celery to Redis, but forget to carryover
transport option `global_keyprefix`. This resulted keys with prefix
`celery-task-meta-` prefix to be created.

This fix unbreaks strict Redis ACLs that allow a single prefix.
