### What problem does this PR solve?
Problem Summary:
Previously, when a load job failed due to data quality issues, the response
only contained an `error_url`. Users had to manually access this URL to view
the error details and the problematic data rows. This process was inconvenient
and slowed down the debugging cycle.
This commit enhances the error reporting mechanism to provide immediate
feedback. Now, the details of the first data quality error encountered are
printed directly in the synchronous load job's response or the BE log.
The new inline error message includes:
- The specific reason for the failure.
- The raw data of the offending row.
This allows users to quickly identify and fix issues in their source data.
For asynchronous jobs like Broker Load, this information is exposed in a new
`FirstErrorMsg` column in the output of the `SHOW LOAD` command.
The `error_url` is still provided for users who need a comprehensive list of
all filtered rows.
