Switch cache infrastructure from Azure Cache for Redis to Azure Managed Redis

[akhan-msft]

Summary

The companion docs article already names Azure Managed Redis as the recommended cache. The Terraform infrastructure still provisions azurerm_redis_cache (Azure Cache for Redis). This issue tracks aligning the implementation with the docs.

What needs to change

• Terraform
• Application code (pom.xml / application.properties)

Acceptance criteria

• Terraform provisions azurerm_redis_enterprise_cluster + azurerm_redis_enterprise_database.
• Private endpoint and DNS zone reference the correct AMR sub-resource and zone.
• App connects and caches data successfully end-to-end after azd up.
• README and any connection string documentation updated.
