feat: add template enhancements (#1154)

## Description

General enhancements for templates.

## Changes Made

Added the following changes to the template flow:
- Allow adding document meta settings
- 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:
- Extract common fields between document and template flows
- Remove the title field from "Use template" since we now have it as
part of the template flow
- Add new API endpoint for generating templates

## Testing Performed

Added E2E tests for templates and creating documents from templates
