🎨 Palette: 외부 링크에 대한 스크린 리더 접근성 개선

대시보드에서 target="_blank" 속성을 사용하여 새 탭에서 열리는 외부 링크에 접근성 경고를 추가했습니다.

💡 What:
scanner/dashboard/index.html 파일의 외부 링크 렌더링 로직에 aria-label="${esc(r)} (opens in a new tab)" 속성을 추가했습니다.

🎯 Why:
스크린 리더를 사용하는 사용자가 링크를 클릭했을 때 갑자기 새로운 컨텍스트(새 탭)로 이동하게 되면 혼란을 겪을 수 있습니다. WCAG 3.2.5 지침에 따라 링크가 새 탭에서 열린다는 것을 명시적으로 알리기 위해 추가했습니다.

📸 Before/After:
Before: <a href="..." target="_blank" rel="noopener">...</a>
After: <a href="..." target="_blank" rel="noopener" aria-label="... (opens in a new tab)">...</a>

♿ Accessibility:
스크린 리더 사용자가 링크를 포커스할 때 "(opens in a new tab)"이라는 문구를 읽게 되어, 시각적 피드백 없이도 컨텍스트 전환을 미리 인지할 수 있습니다.

@seonghobae Found one blocker.

Blocker — missing regression coverage.
scanner/dashboard/index.html Line 284 changes the accessible-name contract for untrusted references values. This commit does not add a test.

Add a dashboard contract test that verifies all of these conditions:

The reference link has target="_blank" and rel="noopener".
The accessible name includes the reference text and (opens in a new tab).
A reference containing ", ', <, >, &, and backticks is escaped in the aria-label attribute.

I verified the implementation details:

esc() escapes all characters required for this double-quoted attribute context.
The aria-label includes the visible reference text. It does not create a new ambiguous name for distinct references.
Identical reference values already represent the same destination and purpose.
The dashboard has no localization layer and uses hard-coded English strings. The new English suffix is consistent with the current interface.

Closing as superseded by the older PR #930 after exact-diff comparison. At current head fab7c5aaca91cabdaccec7f41cf10089c8caf15f, this PR's only production change is the same scanner/dashboard/index.html external-reference aria-label="${esc(r)} (opens in a new tab)" change already present at #930 head 673760e163718c239912595e0c4bf8ccc7c0e8fd. #930 also carries the corresponding accessibility guidance plus focused dashboard regression coverage, while this PR has an unresolved review request for additional regression coverage. Preserving one implementation lane avoids competing writes to the same dashboard artifact; continue the external-link accessibility contract in #930.
