Each direct mailer.sendMail() call is replaced by a dedicated background
job so that email delivery failures can be retried independently.
New jobs: send-pending-email, send-completed-email, send-forgot-password-email,
send-document-super-delete-email, send-recipient-removed-email,
send-document-deleted-emails, send-2fa-token-email, send-resend-document-email,
send-direct-template-created-email.
Existing handlers (send-document-cancelled-emails, send-organisation-member-*,
send-recipient-signed-email) have io.runTask wrappers removed since they
interfere with the job scheduler. Job triggers are dispatched after
transactions commit to avoid race conditions with uncommitted data.
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.
