to fix issue where preceding word was incorrectly wrapped to new line
- Add /api/hash endpoint to compute and cache MD5 hashes on demand
- Extend /api/files response with md5 field for EPUBs (null if not cached)
- Compute and cache MD5 automatically after EPUB uploads
- Add flush() before close() in WebSocket and HTTP upload handlers

directory and invalidated when file size changes.
