Subject: [PATCH] feat(pdf): add overload for Page to apply design across all
 pages

- Introduced Page(Action<PdfPage>) method to apply design logic to every page in the document
- Simplified Background method by replacing per-page iteration with new Page overload
- Improved readability and maintainability by removing duplicate page loop logic
