Remove ExportBook component and integrate new export workflows

- Deleted `ExportBook` component and its usage in `BookCard.tsx`.
- Integrated improved book export workflows in `BookSettingOption` for better user experience.
- Updated database models and repositories to support export options with chapter/version selection.
- Added localization support for export-related messages and tooltips.
- Upgraded dependencies to include libraries required for export formats (e.g., DOCX, PDF, EPUB).
- Bumped app version to 0.4.1.
