1. Add button to Workflow Settings Page
2. Build new form
3. Wire it all up
4. Use the new style toast notification## 1. Add the "Publish Template"/"Update Template" button to the Workflow Settings page

2. Add the new publish/update template form

3. Make it work!

Ensure that published templates appear in the template browser.

4. Add a toast (using the new style toast, not the old style toast shown below)

Acceptance Criteria

1. Permissions match legacy implementation (superuser only)
2. Publish should "save and publish" and this should be displayed in the toast
3. Styles match legacy implementation
4. Chip behavior matches legacy implementation

Basically, this is a 100% port. When testing verify that it matches the existing behavior 100% except for the new "save & publish" functionality
