Put uploaded files on the dashboard

This commit depends on and uses the data returned by:
- [x] https://github.com/alphagov/notifications-api/pull/345
- [x] https://github.com/alphagov/notifications-api/pull/347
- [x] https://github.com/alphagov/notifications-admin/pull/612

It puts the last 5 jobs on the dashboard. This should be changed to all the jobs
from the last 7 days when that parameter is available.

It also:
- links to the jobs page
- makes the numbers on the jobs page consistent with the dashboard
- makes the numbers on an individual job consistent with the appearance of the
  dashboard
