fix: only show reading progress bar in compact view when there is actual progress

- Add conditional rendering for ReadingProgressBar in CompactView
- Only display progress bar when readingProgress > 0
- Remove empty progress bar separator from compact list view
- Maintain clean, minimal compact view without unnecessary visual elements
- Keep progress bar functionality for cards with actual reading progress
