Bug Fix / i18n Quality

🎯 Objective

Fix Twitter Card twitter:label1 ("Reading time") and twitter:label2 ("Article type") to be localized per language. Currently these labels remain in English for all non-English language variants while only the twitter:data1 and twitter:data2 values are translated.

📊 Current State — Evidence from Recent PRs

Affected PRs: All news article PRs — #480, #482, #483, #485

Example — Government Propositions articles:

<!-- In 2026-02-24-government-propositions-de.html (German) -->
<meta name="twitter:label1" content="Reading time">     <!-- ❌ Should be "Lesezeit" -->
<meta name="twitter:data1" content="5 Min. Lesezeit">   <!-- ✅ Correctly localized -->
<meta name="twitter:label2" content="Article type">      <!-- ❌ Should be "Artikeltyp" -->
<meta name="twitter:data2" content="Analyse">            <!-- ✅ Correctly localized -->

<!-- Same pattern in Japanese, Arabic, Chinese, Korean, French, etc. -->
<meta name="twitter:label1" content="Reading time">      <!-- ❌ English in all languages -->
<meta name="twitter:label2" content="Article type">      <!-- ❌ English in all languages -->

Root cause: scripts/article-template.ts lines 347-349:

<meta name="twitter:label1" content="Reading time">
<meta name="twitter:label2" content="Article type">

These are hardcoded English strings. The template already receives a lang parameter but doesn't use it for label localization.

🚀 Desired State

Twitter Card labels localized per language:

🔧 Implementation Approach

1. Add twitterLabel1 and twitterLabel2 translations to the LABELS object in scripts/data-transformers.ts
2. Update scripts/article-template.ts to accept lang and look up localized Twitter labels
3. Run npx vitest run to verify
