This ticket includes:
- Choosing a template shows template data in the popup (fields and descriptions)
- Similar to how VE does it - but show all fields.
- Autovalues should be pre-filled (see API example).
- There should be some indication that required fields are required.
- Show the required fields on top and suggested fields below it and rest of the optional ones below it.
- Submitting the form does nothing (we'll handle that in T186672)
