BREAKING CHANGE: Complete refactoring of the conversion pipeline.
- Replace in-memory Page/PageContainer with disk-based PageFile struct
- Extract archives to temp directory instead of loading into memory
- Use cwebp InputFile/OutputFile for zero-copy file-to-file conversion
- Use cwebp -crop for splitting (no Go-side image decode needed)
- Check if already converted before extracting (fast pre-check)
- Remove oliamb/cutter dependency (replaced by cwebp -crop)
- Remove page_container.go (no longer needed)
- Add comprehensive tests with improved coverage

Consolidates image conversion logic into a dedicated method.
This change streamlines the conversion process by centralizing the
setting of converted image data, extension, and size. It also
introduces a flag to track whether an image has been converted.
The old resource cleanup has been removed since it is not needed anymore.
