Add audit system

[Nsohko]

1. Make it so all entries are 'soft-deleted' => So the should still be retrievable in the future if needed
   I think prisma should support a nice way of doing this, but we will need to look into it

2. Create some kind of auditing table that keeps track of operations on the db
   I think there are probably examples of this online
   If possible, it would be nice to view this by Logs / Admin from the UI. For example :-

• Maybe can see a loan history for each item
• If possible, have a new tab that lists action on the db (and who it is by). Idk if this is possible in a nice way though, if not just the audit table in the db is enough
