Job Chain Details view should show file order source in a single line

Current Situation

• In the Job Chain Details view chains with file order sources are displayed.
• The path and regular expression for a file order source are split across a number of lines should a longer path be used. This is due to the fact that the panel that displays the file order source has a fixed width.
• This behavior forces users to scroll right/down to check the complete path.

Desired Behavior

• The panel to display a file order source should use a dynamic width (or a larger fixed width across the whole window) to prevent paths from being split across a number of lines.
