Enhance RsCodeMirror Component with Quick Dev Features and Improved Formatting

- Added quick development features including toggles for line numbers, word wrap, and active line highlighting to enhance the coding experience.
- Implemented search functionality with keyboard shortcuts for improved code navigation and editing.
- Enhanced JSON formatting capabilities to handle JSON code without relying on Prettier, ensuring better performance for JSON files.
- Updated the component's template and styles to accommodate new features, including a responsive layout for quick dev tools.
- Improved cursor position tracking and display for better user feedback during code editing.
