Improvements regarding inactive Donation Sites

[cielf]

Summary

Allow banks to see inactive donation sites and to restore them

Why

We recently made donation sites deactivatable rather than deletable -- because deleting donation sites also deleted the corresponding donations! The actions we took for that were a stop-gap measure to prevent accidental deletion of donations. This issue addresses the finer details of having deactivatable donation sites -- being able to see the inactive sites, and being able to restore them.
This allows the banks to be able to more easily handle cases where sites may go dormant and reappear -- for example seasonal sites.

Details

1/ The donation site list, seen at Community | Donation Sites should have a filter available on it so that the inactive donation sites can be shown.
2/ The inactive donation sites on that list should have a button next to them, labelled "Restore", that allows for the reactivation of the donation sites

Hint

See Inventory | Items & Inventory for a very similar case.

Criteria for completion

• Filter for donation sites to also include inactive donation sites is availalble on the donation sites list.
• Inactive donation sites can be restored by clicking a button next to them on the donation sites list
