fix(pack): /pack/info reads ItemId via shadow FK, not nav property

Browse Source 
PackController.Info's ownedItemsByItemId projection used `i.Item.Id` to
key the dict — EF translates that to the FK column today, but any future
model change that breaks the nav→column mapping would fall back to client
eval and collapse every key to 0 (the default Item constructor's Id),
silently hiding every tutorial pack via item_number=0. EF.Property<int>
reads the shadow FK directly and is robust to nav changes.
