Query system: long query messages are hard to read with the new DT::datatable() defaults

Line wrapping is now disabled which is undesirable:

This is a result of using the Scroller extension for DataTables. It requires all row heights to be the same. I see a few possible paths forward.

1. Adjust the defaults for a few select tables (such as the one pictured above).
2. Use another plugin like elipsis to truncate long text (still available in tooltip). I could see this as a solution combined with (1), where a table like the queries will have full text and word wrap.
3. Remove the use of Scroller.

Issue with (1) is it can be hard to know which table the end user would want to adjust this default for.
Issue with (2) is that we are adding another plugin. Plus it doesn't really address the problem pictured above without being combined with another solution.
Issue with (3) is that we lose the dynamic rendering. Personally I think removing the paging is a high value add from a user perspective. If we keep the Y-scroll then we need to be mindful about how much data can be rendered at one time. It is unclear if this is a problem or not with how the app is constructed. Also, we would need to come up with a solution for column widths in wide tables.

@jthompson-arcus Thanks for your input. I like the use of scroller in most of the tables. It's just in these two tables that it can be a bit problematic for long query texts.

For now, I think a solution such as 1) and 2) would be nice indeed. I am at the moment finishing a PR that actually does a combination of 1) and 2). However, I saw the ellipsis plugin too late so I implemented something similar (but much less fancy) as no 2) by myself.
