refactor: migrate Redis cache implementation to Valkey with enhanced configurability

Replaced Redis with Valkey as the caching backend across infrastructure and application modules. Updated configurations, templates, and health checks to reflect Valkey-specific parameters. Improved compatibility with enhanced configurability, including max memory and memory eviction policy settings.
