Dashboard Bulk sends section. Reflow

[amazingphilippe]

Description of issue

The bulk sends table on the Dashboard page shows overlapping content when screen width is at 320 pixels.

Potential fix

• Allow the table to overflow, and make sure we can scroll it. We have a scrollable table component we can use, or we can also take the opportunity to make a better one, since the one we have is very JS heavy. Maybe some neat things to do with CSS...
• Not use a table? Though it could create more a11y issues than it fixes.

• Under engineered responsive tables
