dawarich_redis was the last redis instance still on 7-alpine; the
closed PR #10 kept it as an "Ignored or Blocked" entry in the Renovate
Dependency Dashboard (issue #6). Bump to the already-running
redis:8.8.0-alpine digest and add apps/dawarich to the renovate redis
8.x allowedVersions pin. Data path /mnt/user/appdata/dawarich/redis
unchanged; redis 8 loads the existing RDB snapshots.
