Note:

• Major Refactor: PDFBox Integration: Tried Replacing ENgine with iText7 but it was working as expected, but the issue is license. It doesn't provide free license for commercial use, so Migrated the core engine back to PDFBox (Apache 2.0 license) for full legal compliance and maximum efficiency . And exploring iText7 helped me to add many more fature out of pdfbox. I'm just trying to add features that are not offered by pdfbox directly.
• Breaking Change: Enhanced API Structure: Unified and streamlined the PdfUtils API with cleaner models (PdfValidity, PdfPageSize) and more consistent method naming across Dart and Native.
