General enhancements for templates.

## Changes Made

Added the following changes to the template flow:

- Allow adding email settings
- Allow adding document access & action authentication
- Allow adding recipient action authentication
- Save the state between template steps similar to how it works for
documents

Other changes:

part of the template flow
- Add new API endpoint for generating templates
