- Set container width to 100% so column widths can be calculated properly
- Sets duplicates, level, timestamp, local time to a fixed width based upon em units since the size of these are static
- Sets labels to be 20%
- Remove min-width:80% on message column so that it now consumes remaining space
- Additionally fixes long labels from overflowing into the messages column by properly setting a max-width per label and hiding overflow

closes #15673
