5f776f896f Enhance FilePreview Component with Download Progress Indication
All checks were successful
farmcontrol/farmcontrol-ui/pipeline/head This commit looks good
- Integrated download progress tracking in the FilePreview component to provide users with real-time feedback during file loading.
- Updated fetchFileContent function in ApiServerContext to support progress callbacks, enhancing user experience during file downloads.
- Refactored rendering logic in FilePreview to display a progress overlay while files are being fetched, improving visual feedback and interaction.

49e23299da Enhance FileInfo and GCodePreview Components with Loading State and Theme Support
- Wrapped FilePreview in a Spin component to indicate loading state when fetching file data in FileInfo.
- Removed hardcoded color properties from GCodePreview and implemented dynamic theme color support based on user settings.
- Refactored camera and control handling in GCodePreview for improved user interaction and responsiveness.
- Updated File model to include 'extension' field for better file management and sorting capabilities.
