fix: Add layout files for issue #318 and improve camera capture component

- Added `318.html` and `318.mjs` for documenting layout problems related to the split panel.
- Updated `camera-capture.mjs` to enhance formatting and structure in imports and methods, ensuring better readability and maintainability.
- Refined error handling and logging throughout the component to prevent potential uncaught exceptions.
- Organized component dependencies more clearly to eliminate redundancies and improve performance.
- Improved inline comments to clarify the intent and functionality of existing code.

This refactoring not only resolves layout-related issues but also aids future developers in navigating and understanding the codebase.
