feat(conversion): add eBook to PDF via Calibre (EPUB/MOBI/AZW3/FB2/TXT/DOCX) (#4644)
This pull request adds support for converting common eBook formats
(EPUB, MOBI, AZW3, FB2, TXT, DOCX) to PDF using Calibre. It introduces a
new API endpoint and updates the configuration, dependency checks, and
documentation to support this feature. Additionally, it includes related
UI and localization changes.

**New eBook to PDF conversion feature:**

* Added `ConvertEbookToPDFController` with a new
`/api/v1/convert/ebook/pdf` endpoint to handle eBook to PDF conversion
using Calibre, supporting options like embedding fonts, including table
of contents, and page numbers.
* Introduced `ConvertEbookToPdfRequest` model for handling conversion
requests and options.

**Configuration and dependency management:**

* Updated `RuntimePathConfig`, `ApplicationProperties`, and
`ExternalAppDepConfig` to support Calibre's executable path
configuration and dependency checking, ensuring Calibre is available and
correctly integrated.

presence.
