license-barcode-format-discrepancies.md is an orphaned page not linked from any index

Found while reviewing docs in PR #30.

File: barcode-reader/web/scan-setting/license-barcode-format-discrepancies.md

This page exists but isn't linked from scan-setting/index.md, nor referenced anywhere else in the repo (checked _data/full_tree.yml too). Needs a decision on the right link text/placement and adding it to the index, unless it's intentionally hidden.

The content in this FAQ needs a refresh.

Because it isn't linked from the list in index.md, I think it should be marked as archived and placed inside archived.
