Fixes #12199
Motivation
In the Dataproxy Go SDK, sending on the already-closed sendFailedBatches, retryBatches, or responseBatches channels during shutdown can raise a "send on closed channel" panic and crash the process.
Modifications
Introduced a
safeSendhelper that recovers from the closed-channel panic when sending on these channels, and marks the batch as done to release its resources when the send fails.Verifying this change
