Upload Profile Photos to Blob Storage: Code Review Practice

Users can finally set a profile photo. The new endpoint accepts an image upload, stores it in a profile-photos blob container, and saves the blob URL on the user so the web and mobile apps can show it. The container is created at startup if it doesn't exist. There's a test for a successful upload.
