(refactor): Ban Snapshot optimizations

• No need to snapshot/restore personal indexes
• No need to snapshot/restore lookup indexes
• No need to snapshot/restore entities (they can just add the 'delete' boolean to them)
• No need to download from ES (a boolean on all the owner_guids documents should suffice)
• There needs to be a distinction between hiding/deleting. Add another function called hide(), and if it is a delete operation for that delegate, it will just pass though as delete().
