Add a verification code to ANY item.

### Expected Result

Go to the verification to find that only the specific item contains that code.

### Actual Result

Go to the verification section to find that MULTIPLE items also have that verification code (same code and timing) without having it registered to that item.

### Issue Tracking Info

- [x] I understand that work is tracked outside of Github. A PR will be linked to this issue should one be opened to address it, but Bitwarden doesn't use fields like "assigned", "milestone", or "project" to track progress.

No source file or test is named. Start by reproducing the issue on the reported iPadOS build: add a verification code to one item and inspect the verification section for other items. Done means only the item with the registered code displays that code and timing.
