1. I'm not sure what the default sort is, none of the columns show a selected sort when the page loads
2. I can only expand a row by clicking on the arrow, it would be nice if the click target was larger. perhaps clicking the rule name could also expand its row?
3. summarizing how many pass/fails/warnings could be beneficial for at a glance digestibility as this scales across rules and multiple components
4. effective on isn't that useful right now. will it be more helpful in a production setting, or should we look at removing it from the column here, and making room for other information (like the failure message)?

Acceptance criteria:

• make external icon size small
• short status column by default
• make the expandable click area bigger
• show the result summary as per UX
• surface collection on the expanded row as per UX
• remove `effective from` column and show `effective from` in expanded row
• show failure message in the table column, remove from expandable section. Truncate longer failure message and show them in tooltip
