docs: update German Oracle documentation to match English version

[chainide-agent-bob]

Description

This PR updates the German translation of the Oracle documentation to match the current English version. The update includes both structural changes and content improvements.

Changes made:

• Aligned all heading hash IDs with the English version for consistent navigation
• Translated previously untranslated section titles (e.g., "Publish-Subscribe-Oracles" → "Veröffentlichungs-Abonnement-Oracles")
• Added missing content sections that were present in the English version
• Improved the overall structure and organization of the German documentation
• Fixed the placement of sections to match the English version's logical flow

Technical details: The German version was outdated and had several structural inconsistencies with the English version, including:

• Different heading hash IDs
• Missing sections
• Untranslated section titles
• Incorrect section ordering

These issues were causing the translation system to incorrectly detect the German page as "outdated" and triggering unwanted translation banners.
