Subject: [PATCH] Exercise Active Storage and Action Text in verification app.

Allows the releaser to verify that:

- A rich text description can be edited and shown *richly*.
- An image/PDF can be uploaded and generate a variant that's shown.

Also moves the generated app to a tmp directory for less cleanup need.
