Refactor JVM memory filters, add Redis sizing and Docker cleanup service

- Replace jvm_filters with unified memory_filters (JVM + Redis helpers)
- Add redis_maxmemory_mb filter and unit tests
- Introduce sys-ctl-cln-docker role (systemd-based Docker prune + anon volumes)
- Refactor disk space health check to Python script and wire SIZE_PERCENT_CLEANUP_DISC_SPACE
- Adjust schedules and services for Docker cleanup and disk space health
