Review-Nachrichten: konsistentes Styling in History, Chat und Shared-Links

- renderMarkdown: [Review: Agent], [Review-Feedback ...], [APPROVED] Tags parsen
  → styled HTML-Header bzw. ausgeblendet (zentral für alle Views)
- history.js: Review-Messages als .review-bubble rendern statt .assistant/.user
  Review-Messages vom Merging ausgenommen
- shared-page.js: Review-Messages erkennen → .review-bubble Klasse
  Merge-Logik schützt Review-Messages vor Zusammenführung
- addReviewBubbleStatic(): Neue Funktion für History-Rendering mit allen
  Buttons (Reply, Delete, Mark, Share)
- chat.css: .review-inline-header, .review-inline-feedback Styles
