fix(store): add error details to log output during header batch write

[tzdybal]

Overview

The log output has been updated for a better troubleshooting experience when writing a batch of headers. Previously, when an error occurred, the log provided 'from' and 'to' ranges without specifying the actual error. Now, the 'err' parameter has been added to provide more information about the exact issue.
