Release v1.9.2: Full-width background for code blocks

Fixed code block and ASCII art background to extend full paragraph width:
🔧 Background Fix:
- Moved shading (w:shd) from run level (<w:rPr>) to paragraph level (<w:pPr>)
- Background now extends full width like in the preview
- Applied to both createCodeBlockXml() and createAsciiArtXml() functions
📝 Technical Changes:
- src/wordTemplateExporter.js: Paragraph-level shading for full-width backgrounds
- Added w:ind with left="284" right="284" for consistent margins
- Removed redundant w:shd from run properties
