feat: add direct templates links (#1165)

## Description

Direct templates links is a feature that provides template owners the
ability to allow users to create documents based of their templates.

## General outline

This works by allowing the template owner to configure a "direct
recipient" in the template.

When a user opens the direct link to the template, it will create a flow
where they sign the fields configured by the template owner for the
direct recipient. After these fields are signed the following will
occur:

- A document will be created where the owner is the template owner
- The direct recipient fields will be signed
- The document will be sent to any other recipients configured in the
template
- If there are none the document will be immediately completed

## Notes

There's a custom prisma migration to migrate all documents to have
'DOCUMENT' as the source, then sets the column to required.
