Fix edit form content extraction - show clean customer view

🐛 Problem: Edit forms showed client view with edit buttons/emojis
✅ Solution: Extract clean content without edit interface elements

🔧 Changes:
- extractContentFromElement() now properly removes all edit UI
- Improved htmlToMarkdown() for better rich content conversion
- setupEditableElement() preserves original clean content
- Enhanced whitespace normalization in markdown conversion
- Handles both simple text and rich markdown content types

🎯 User Experience:
- Client sees: Content with edit buttons (✏️)
- Edit form shows: Clean, properly formatted content
- Customer sees: Original clean content (no edit UI)

✨ Whitespace improvements:
- Removes excessive indentation and spacing
- Normalizes line breaks and paragraph spacing
- Clean, readable content in edit forms

Critical fix for proper edit-in-place functionality
