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.
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.
