Fix SpotBugs violation in getRepushInfo route

The gRPC response from the handler was not being used - instead, the code
was calling admin.getRepushInfo() directly. This fix adds a conversion
method to properly map RepushInfoGrpc and VersionGrpc to their Java
counterparts and uses the converted response.
