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

templates.
Adds next recipient dictation functionality to document signing flow,
allowing assistants and signers to update the next recipient's
information during the signing process.
