CA-145341: G11n: SC: Overlap and Truncated strings in "Workload Reports" dialog.

For issue 1, move the "labelStartDate" location to left with 4 points.
This would make the gap between "labelStartDate" and "StartDatePicker" larger than others under Windows EN.
For issue 2, would not extend the size of "StartDatePicker" and "EndDatePicker" since they would occupy other labels and comboBoxes' room.
