stdout sytle updates

* Fixed column width to 50% for both job stdout view and inventory update
script output view
* Fixed scrolling behavior so we don't have two elements doing scrolling
(inner was doing width, outter was doing height)
* Reduced max height for stdout jt output view to 900px down from
1600px
* Flexified inner output window on inventory script output view so the
gray output area always fills the height of the panel
