Describe the bug

When looking at the netbox interfaces view in the room search the filtering by "Last seen (days ago)" does nothing. Only entering a very high number (e.g. 100000) will result in "No matching records found". Any reasonable number of days leads to no change.

The sorting by the "Last active" column also does not work.

To Reproduce

Steps to reproduce the behavior:

1. Go to /search/room/<room_id>/#!netboxinterfaces
2. Enter a number in the Last Seen (days ago) field (or click on the arrows next to the Last active column)
3. See that nothing changes

Expected behavior

For the interfaces that were seen less than x days ago to be filtered out and to be able to sort by Last active.
