Fixes browse button being hard to click

### Notes
* The mouseover event that fixes this issue had not been properly binding to the input when being called in the rendered event, so it's moved to the display method and now works. Very thankful for @jtferns's investigation!

I also made a small markup change so that the input/label for VSAC Effective Date lines up with the rest of the parts of the dialog.
