[Spaces] Spaces page table has lots of ellipsis

[florent-leborgne]

Kibana version: 8.16

Environment: QA

Describe the bug: Columns of the Spaces table aren't optimized, resulting in too many ellipsis, while the column for the description is too large. In 8.16 QA:

Comparison with 8.15:

Steps to reproduce:

1. Create an 8.16 stateful deployment on QA
2. Go to Stack Management > Spaces and add a few more spaces
3. Resize the browser window to notice the lack of optimization in responsiveness, even at max width.

Expected behavior: Features visible and Solution view columns + content fit without ellipsis, and smaller Description column.
