Handle loitering objects that are stationary

[NickM-27]

Proposed change

The review maintainer only looked at active objects. This means if an object became stationary before the loitering time was met then the review item would not be created. This PR makes the following changes:

• Create a pending_loitering attribute for objects to signify if they are in a zone with loitering time set
• Review items with loitering objects will stay "ongoing" as long as the object is loitering in the zone, because the user has configured that they care about an object loitering in that area
