fix(ItemRepository): improve used fields in specific queries

[theEvilReaper]

Proposed changes

Some queries were copy-pasted and kept their original field access, which led to mismatched contexts and incorrect data fetching. This pull request fixes the queries so they fetch the correct data for their intended context.
