Balázs Szücs 1318604f32 [V2] feat(convert): add eBook (EPUB, MOBI, AZW3, FB2) to PDF conversion options and UI (#5291)
# Description of Changes

This pull request adds support for converting eBook formats (EPUB, MOBI,
AZW3, FB2) to PDF, including a new set of user-configurable options for
the conversion process. It introduces frontend UI components, updates
configuration and constants, and ensures that the backend can recognize
and handle these new formats and options.

**eBook to PDF Conversion Support**

- Added support for converting eBook formats (`epub`, `mobi`, `azw3`,
`fb2`) to PDF, including updates to conversion endpoints, extension
mappings, and conversion matrices in `convertConstants.ts` to route
these conversions through the new `ebook-to-pdf` endpoint.
- Updated the file processing logic so that eBook-to-PDF conversions are
processed separately for each file, similar to web file conversions.

**Frontend: User Options for eBook Conversion**

- Added a new UI component `ConvertFromEbookSettings.tsx` that allows
users to configure options for eBook-to-PDF conversion: embedding all
fonts, including a table of contents, adding page numbers, and
optimizing for eBook readers. This component is conditionally rendered
in the conversion settings when an eBook format is selected as the
source and PDF as the target.
- Integrated the new eBook options into the conversion parameters and
ensured they are initialized/reset appropriately in the conversion
settings.
**Form Data and Backend Integration**

- Modified the form data builder to append the new eBook options to the
request payload when performing eBook-to-PDF conversions, ensuring these
settings are sent to the backend.

**Localization and Configuration**

- Added localization strings for all new eBook conversion options in the
English translation file, providing user-friendly labels and
descriptions in the UI.
- Updated backend configuration logic to recognize `Calibre` and
`FFmpeg` as tool groups, ensuring correct enablement/disablement
behavior for these tools.
