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.
## Description
Currently if you complete a pending encrypted document, it will prevent
the document from being sealed due to the systems inability to decrypt
it.
This PR disables uploading any documents that cannot be loaded as a
temporary measure.

This is a client side only check
## Changes Made

a blend of client and server actions.
