### Description of PR
This PR adds an optional FedBalance verification phase after the final
DistCp succeeds.
The verification is disabled by default. When enabled, FedBalance compares
the source and destination ContentSummary directory count, file count, and
length after excluding snapshot content. A mismatch fails the job, while
transient ContentSummary read failures are retried by the procedure scheduler.
This provides a lightweight built-in verification mechanism without changing
the default FedBalance behavior.
### How was this patch tested?
Ran FedBalance unit tests locally and validated on a production cluster.
### AI Tooling
Contains content generated by Codex.
