What changes were proposed in this pull request?
Recon reports healthy EC containers as REPLICA_MISMATCH because it compares checksums across different replica indexes, which contain different data or parity fragments.
This change compares EC checksums only between replicas with the same index, while preserving the existing comparison for non-EC containers. It uses the replicas available during each Recon health scan.
