server/configuration/index.md: Aztec-code archive entry may not belong in server FAQ

[lyzhang0113]

Found while reviewing docs in PR #30. Only the broken link path was fixed there (see PR #30); this is a separate content-placement question.

File: barcode-reader/server/configuration/index.md

This index links to barcode-reader/server/archive/unable-to-scan-aztec-code.md, but that archived page's content is JS-edition-specific (Dynamsoft.DBR.BarcodeScanner._bUseFullFeature, compact-vs-full engine terminology) and duplicates barcode-reader/web/scan-setting/unable-to-scan-aztec-code.md, which is already properly linked from the web FAQ index.

Also, the parent index barcode-reader/server/index.md doesn't link to this entry at all, while configuration/index.md does — the two indexes disagree about whether this page belongs in the server docs.

Worth deciding: should this entry be removed from the server FAQ (since it's really web-edition content), or is there server-specific content that got merged into the wrong archive page?

Fixed via #55 (now merged into faq-docs-quality-pass, and the commits are also directly on that branch as of commit 7605815): removed the duplicate archive file and its entry in server/configuration/index.md. Leaving open until faq-docs-quality-pass merges to preview (PR #30).
