Items stored in a rentable shop due to the store being closed/taken over will now be deleted after 24 hours (realtime)
See RentableShop.MaxStoredItemsDurationMinutes convar, as well as AdditionalCheckTimeHoursDebug for debugging/testing
Any save files loaded after this changeset will clear any pre-existing stored items after 24 hours from the point of load (since we weren't saving the timestamp)
If a player has their items stored multiple times in a 24 hour window the original deadline will apply, it cannot be extended
