Bug 32752: Use an include to display the serial status in the staff interface

This moves the identical code used to display the serial status
from the different templates into one common include.

To test:
* Add a subscription
* Receive several issues, make sure 2 are late
* Claim one of the late issues
* Verify the status displays nicely on these pages:
  * Subscription detail page > issues tab
  * Catalog detail page > subscription tab
  * Serial claims page
  * Serial collection page of your subscription

Note: there was some code for the subscription detail page
that should have displayed the claim date, but didn't work.
To keep things simpler and identical to before, I have left
that bit out for now.
