Bug 22287: Correct new charts CSS

This patch reverts some changes to reports CSS from Bug 22168 which were
unnecessary and which adversely affected the report add/edit form
styling.

To test, apply the patch and clear your browser cache if necessary.

Go to Reports -> Saved reports and repeat the test plan for Bug 22168:

- Run a report which returns more than one column.
- On the report results page, click the "Create chart" button. The chart
  settings form should appear in a modal window.
- Click the "Draw" button. The modal should disappear and the chart
  should be shown.

Then test the process for adding or editing an SQL report. The form
should be styled in a way consistent with other forms in the staff
client.
