The git changes introduce functionality to merge attachments from a processed ZIP archive into a single PDF file. Here is a summary of the changes: ### New Features - PDF Merging: Added the ability to merge multiple attachments (PDFs and images) from a processed ZIP archive into a single PDF document. - Image Conversion: Implemented automatic conversion of non-PNG images (like JPGs) to PNG format before embedding them into the merged PDF. ### File Changes - Dependencies: Added pdf-lib to the project's dependencies. - src/lib/zip-processing.ts:

- Added mergeProcessedZipArchive to handle the core logic of creating a merged PDF.                         - Implemented helpers to embed PDF pages and convert/embed images.     - Added toArrayBuffer and convertImageBytesToPng utilities for handling binary data and canvas-based image processing.
     - src/lib/components/ProcessedZipArchiveEditor.svelte:
 - Added a "PDF herunterladen" (Download PDF) button.              - Added UI states to handle the merging process (loading state, error messages).
     - Integrated the mergeProcessedZipArchive function with the UI.
      - src/lib/components/AttachmentPreview.svelte:
 - Added a fix to ensure attachment.data is treated as a Uint8Array when loading PDF documents.
