Enhance Thumbnail and ApiServerContext components for improved functionality

- Removed the default border style from the Thumbnail component to streamline its appearance.
- Updated the Thumbnail component to dynamically set the width in the card styles, enhancing layout flexibility.
- Modified the fetchFileThumbnail function in ApiServerContext to include an optional parameter for handling 404 errors, improving error management during thumbnail fetching.
- Added a thumbnail property to the GCodeFile model, enabling thumbnail support for GCode files.
