feat: add test excalidraw page with deep linking support

- Added new test excalidraw page component and route with deep linking via ?tests=excalidraw
- Enhanced drawings editor to preserve frontmatter and normalize metadata when saving .excalidraw.md files
- Improved excalidraw file handling with better error handling and sanitization
- Updated sidebar and navigation to include test excalidraw option
- Fixed collaborators map serialization issue in excalidraw scene data
