[V2] feat(convert): add support for CBR to PDF and PDF to CBR conversions (#4833)

# Description of Changes TLDR: - Introduced `ConvertFromCbrSettings` and `ConvertToCbrSettings` components for handling conversion-specific settings. - Updated `ConvertSettings` to include CBR-related configurations. - Updated `useConvertParameters` with new parameters: `cbrOptions` and `pdfToCbrOptions`. - Updated locales with CBR-related translations. - Added endpoints and updated conversion matrix for CBR formats in `convertConstants`. - Modified `useConvertOperation` to handle CBR-specific parameters during form data preparation. For backend see this PR: #4581 This pull request adds support for converting between CBR (Comic Book Archive) and PDF formats in the frontend. It introduces new UI components for configuring conversion options, updates the conversion constants and logic, and ensures parameters for these conversions are handled correctly throughout the app. **CBR/PDF Conversion Features:** * Added new UI components: `ConvertFromCbrSettings` for CBR to PDF conversions (option to optimize for ebook readers), and `ConvertToCbrSettings` for PDF to CBR conversions (DPI selection for image rendering). These are conditionally rendered in `ConvertSettings.tsx` based on selected formats. **Conversion Logic and Constants:** * Extended conversion endpoints, format options, conversion matrix, and endpoint mappings to support CBR to PDF and PDF to CBR conversions. * Updated `shouldProcessFilesSeparately` logic to handle PDF to CBR conversions, ensuring each PDF generates its own archive. **Parameter Handling:** * Added new parameters (`cbrOptions` and `pdfToCbrOptions`) to the conversion parameter interface and default values, ensuring they are set/reset appropriately during format changes * Modified form data construction to include new options for CBR/PDF conversions (optimize for ebook, DPI). ### Frontend <img width="1291" height="861" alt="image" src="https://github.com/user-attachments/assets/fb63be66-6f40-4dde-8235-86c9ddfa1f7c" /> <img width="1411" height="1000" alt="image" src="https://github.com/user-attachments/assets/529593c4-6f32-4b11-9754-7f334f40d32e" /> Note on RAR5. You can go back-and-forth with this converter due to the fact on default pdf to cbr makes RAR5 meanwhile, cbr to pdf can only RAR4 and below. This is unfortunate limitation of JunRAR library. In the real world, generally RAR5s are not that common, and they mostly unsupported by open-source software.  --- ## Checklist ### General - [X] I have read the [Contribution Guidelines](https://github.com/Stirling-Tools/Stirling-PDF/blob/main/CONTRIBUTING.md) - [X] I have read the [Stirling-PDF Developer Guide](https://github.com/Stirling-Tools/Stirling-PDF/blob/main/devGuide/DeveloperGuide.md) (if applicable) - [ ] I have read the [How to add new languages to Stirling-PDF](https://github.com/Stirling-Tools/Stirling-PDF/blob/main/devGuide/HowToAddNewLanguage.md) (if applicable) - [X] I have performed a self-review of my own code - [X] My changes generate no new warnings ### Documentation - [ ] I have updated relevant docs on [Stirling-PDF's doc repo](https://github.com/Stirling-Tools/Stirling-Tools.github.io/blob/main/docs/) (if functionality has heavily changed) - [ ] I have read the section [Add New Translation Tags](https://github.com/Stirling-Tools/Stirling-PDF/blob/main/devGuide/HowToAddNewLanguage.md#add-new-translation-tags) (for new translation tags only) ### Translations (if applicable) - [ ] I ran [`scripts/counter_translation.py`](https://github.com/Stirling-Tools/Stirling-PDF/blob/main/docs/counter_translation.md) ### UI Changes (if applicable) - [X] Screenshots or videos demonstrating the UI changes are attached (e.g., as comments or direct attachments in the PR) ### Testing (if applicable) - [X] I have tested my changes locally.
