Fix 0011927: html_status_legend has code paths that return invalid HTML

The html_status_legend function in html_api.php first prints opening table tags such as <table>. There are then code paths within the function that return without adding the closing </table> etc tags to the table. This causes rendering problems in browsers as the output HTML can be invalid.
