[ci skip] Phase 2: migrate Redis from NFS to local disk

Browse source

- Switch from redis/redis-stack:latest to redis:7-alpine
  (modules were completely unused — zero module commands in stats)
- Move data from NFS (/mnt/main/redis) to local-path PVC
  (RDB saves: 39s on NFS → <1s on local disk)
- Start fresh (old RDB had redis-stack module data incompatible with plain redis;
  all Redis data is transient — queues and caches rebuild automatically)
- Add hourly redis-backup CronJob: redis-cli --rdb to NFS for backup pipeline
- Remove RedisInsight UI ingress (port 8001, only in redis-stack)
- Add redis-backup to NFS exports
- 110 clients reconnected immediately after switchover
- Memory savings: ~100MB from dropping unused modules
