Adds support for an `externalId` query param to be passed when linking a
user to a direct template. This external id will then be stored on the
document upon signing completion.

template to allow for custom email bodies and subjects for documents
created from direct templates.

## 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.
