Fix(wren-ui): fix previewSql mutation for doing dry run

[onlyjackfrost]

• Throw an GraphQL error back to the client instead of returning false
• The GraphQL error contains the error code DRY_RUN_ERROR and the error message from ibis/wren-engine back to the client

Example GraphQL response when failed
