Refactored Redis resource include macro and increased memory limits

- Replaced deprecated lookup(vars=...) in svc-db-redis with macro-based include (Ansible/Jinja safe)
- Redis now uses higher resource values (1 CPU, 1G reserved, 8G max, 512 pids)
- Enables stable Whiteboard operation with >3.5 GB Redis memory usage
