HDDS-15261. Increment UNHEALTHY count when a container reaches sufficient unhealthy replicas

[sarvekshayr]

What changes were proposed in this pull request?

Fixed a regression from HDDS-14119 in RatisUnhealthyReplicationCheckHandler, where the UNHEALTHY container count was not being incremented in reports. While the handler correctly identified under- and over-replicated containers, it missed the count for containers that were sufficiently replicated but unhealthy. Added an explicit check to ensure these containers are accurately tracked after the replication health checks are performed.
