refactor: update ErrorElement and HistogramChart components for improved styling and functionality

- Enhanced the ErrorElement component by adjusting the layout for better centering and added select-text class for improved text selection.
- Modified the HistogramChart component to accept a thumbnail URL instead of tone analysis, streamlining the data flow.
- Refactored the histogram calculation logic to improve performance and clarity, including compression of histogram data.
- Updated the manifest version from 'v2' to 'v3' across multiple files to reflect the new data structure.
