* style(sqllab): make database errors more clear and render as monospace
In SQL Lab, when a database error message is returned, generally because
of a user error in the SQL, it's identified as an "Unexpected Error" and
some of the text formatting of the error message (\n, spaces, tabs, ...)
are lost as they are rendered in html.
This PR identifies the error as a "Database Error", and renders like
more like a <pre>, using a monospace font.
