Update context listing page per new design
## Problem/motivation
Follow-up to:
#3586140
There is a new design for the context listing page based on UX review and feedback.
## Solution
1. Type: Manual => Text
2. Subcontext type icon needs to pass contrast checker
3. Tokens in own column is good
4. No icon for yellow (medium) and grey (low) token numbers
5. Warning icon for red (high) token numbers
6. No info icon after context items
7. Scope column is good
8. Keep use cases column separated
9. Target => scope (but minimize what's shown)
10. Updated => Status (draft/published/unpublished)
11. Target dropdown => Scope dropdown? or just search scope with the text box #3574924
