Updated Trac query styling to be more compact and support mobile.

[sarahboyce]

Changes:

• updated the default queries to add the description search to be available by default (as if a permanent search bar)
• reduced the columns in the default view (also nicer for mobile, ignore the image here, I do not have all columns available locally)
• reduced general use of margin
• the paging option at the top of the table is now hidden
• the options for grouping, showing the description under each desult, changing the page side is hidden for guests - this is to make the page less noisy on first visit

No worries if it's not the right way to go with it, just thought I would have a play 👍 got me set up with the project

Also added mobile support

I've been looking for a way to add the description search field by default, would be great to at least have that added.

Oooh… this looks fun @sarahboyce 🤩

I could particularly do with this for the Timeline view

This seems like a clear improvement over the status quo.

Love this, thanks for picking it up! 🚀

I think there's a few easy wins that we could already merge, but the CSS changes would require a more thorough review (we need to consider other pages that use the stylesheet, not just the ticket list).

Do you have the bandwidth to split things out into separate commits, or would you prefer if I did it?
