[Translation] German (DE) - Translate 12 core + product pages (key European market)

[pethers]

🎯 Objective

Translate the body content of 12 German core + product pages from English to professional German. Germany is Hack23's largest European market outside Scandinavia.

📋 Background

Previous issue analysis: No German-specific translation issue was ever created. German currently has 56/96 files (58%) still containing English body text. Core and product pages are the most customer-facing.

Previous Copilot completion rate was ~0% because issues were too large (84-145 files). This issue targets only 12 files.

🛠️ Implementation Guidance

For each file:

1. Find the <article> or <main> section with English paragraphs
2. Translate all text content (<p>, <h2>-<h6>, <li>, etc.) to German
3. Keep all HTML tags, attributes, links, images intact
4. Use index_de.html for terminology consistency
5. German cybersecurity terms: "Cybersicherheit", "Informationssicherheit", "Schwachstellenmanagement", "Zugriffskontrolle"

Reference:

• "Services" → "Dienstleistungen"
• "Products" → "Produkte"
• "Security" → "Sicherheit"
• "Compliance" → "Compliance" (same in German)
