Marko (Hermes Implementer) 74fdae61db Resolve merge conflicts for PR #25: customizable mobile reading experience
- Backend: Replace PR's Book-only models with main's full models
  (EBook, BookChapter, DownloadRecord, ReadingProgress, ReadingSettings)
- Backend: Add reader app (ReadingSettings model, serializer, view, URL)
- Frontend: Port reader feature files from web/ to frontend/ (api, hooks,
  components/reader/, pages/ReadingPage, types/reader, reader.css)
- Frontend: Add /read/:id route to App.tsx for chapter-based reading view
- All imports adjusted for frontend/src directory structure
