[V2] feat(convert): add support for CBZ to PDF and PDF to CBZ conversion (#4831)
# Description of Changes


TLDR:
- Implemented `ConvertFromCbzSettings` component for CBZ to PDF options
- Added `ConvertToCbzSettings` component for PDF to CBZ options
- Extended conversion constants with new CBZ-related formats and
mappings
- Updated `ConvertSettings` to include CBZ-specific configuration forms
- Updated `useConvertOperation` to handle CBZ conversion parameters

For backend reference see this PR: #4472

This pull request adds support for converting between CBZ (Comic Book
Zip) and PDF formats in the frontend conversion tool. It introduces new
UI components for CBZ-to-PDF and PDF-to-CBZ conversion options, updates
the conversion parameters and form data logic, and integrates these
formats into the available conversion options and endpoints.

**CBZ/PDF Conversion Support:**

* Added `ConvertFromCbzSettings` and `ConvertToCbzSettings` components
to provide user options for CBZ-to-PDF and PDF-to-CBZ conversions,
including "Optimize for ebook" and DPI settings.

**Conversion Logic and Parameters:**

* Extended the `ConvertParameters` interface and default parameters to
include `cbzOptions` (for CBZ-to-PDF) and `cbzOutputOptions` (for
PDF-to-CBZ).

**Conversion Matrix and Endpoint Integration:**

* Added CBZ to the supported "from" and "to" format lists, updated the
conversion matrix to allow CBZ-to-PDF and PDF-to-CBZ, and mapped the new
conversions to appropriate API endpoints.
* Updated URL mapping to recognize `/cbz-to-pdf` and `/pdf-to-cbz` as
conversion tool routes.
