feat: add PHP preprocessing for Mermaid code blocks
- Add argon_format_mermaid_code filter in functions.php - Decode WP-Markdown escape characters in PHP - Auto-add newlines for single-line mermaid code - Simplify JavaScript rendering logic - Use data-mermaid-code attribute for preprocessed code - Remove debug console.log statements
