Some widgets are too large for small displays

E.g. in general the music widget takes up a lot of horizontal space. Some options to explore:

- Adding an "extra small" widget size.
- The Now Playing can be configured to just show album art.

The issue names no files, tests, or entry points. Start by reproducing the music widget on a small display and comparing the proposed extra-small size with the Now Playing album-art-only option. Done means an agreed approach makes the affected widgets fit small displays without losing the required information.
