Pull Request Overview

Enhance font formatting support for pasted Word and PowerPoint lists by extracting bullet element styles and applying them to the list-item marker, and update tests to assert the new behavior.

• Parse and apply the actual bullet element’s font styles to formatHolder in processAsListItem.
• Update Word and PowerPoint unit/E2E tests to expect the new fontFamily and fontSize on list markers.
• Add a new E2E HTML template (wordClipboardContent2) and associated model setup for Word list paste scenarios.
