Subject: [PATCH 1/2] Improve error handling for item retrieval

Fix: Return 404 for non-existent items instead of null response

Previously, valid ID formats with non-existent items returned 200 OK
with null values, creating ambiguous API responses. Now properly returns
404 Not Found when items don't exist in the database.
