refactor: replace pdf-sign with libpdf/core for PDF operations (#2403)

Migrate from @documenso/pdf-sign and @cantoo/pdf-lib to @libpdf/core
for all PDF manipulation and signing operations. This includes:

- New signing transports for Google Cloud KMS and local certificates
- Consolidated PDF operations using libpdf API
- Added TSA (timestamp authority) helper for digital signatures
- Removed deprecated flatten and insert utilities
- Updated tests to use new PDF library
