Easier and improved sorting

We have improved the way data is ordered on overviews and made it easier to spot and change the sorting order.

The recommended sort order does depend on the page and sidebar filters applied.

• Last modified when filtering for drafts
• Scheduled Date when filtering for scheduled campaigns
• Sending Date when filtering for sent campaigns
• Relevance when user filters using search term
• and so on

Ordering can be changed using the dropdown `sort by` on the right or by clicking column headers on the overview.
