This PR introduces automatic detection and placement of fields and
recipients based on PDF placeholders.
The placeholders have the following structure:
- `{{fieldType,recipientPosition,fieldMeta}}`
- `{{text,r1,required=true,textAlign=right,fontSize=50}}`
When the user uploads a PDF document containing such placeholders, they
get converted automatically to Documenso fields and assigned to
recipients.
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
This PR is handles the changes required to support envelopes. The new
envelope editor/signing page will be hidden during release.
The core changes here is to migrate the documents and templates model to
a centralized envelopes model.
Even though Documents and Templates are removed, from the user
perspective they will still exist as we remap envelopes to documents and
templates.
