This PR adds flex wrapping to the annotation header bar so the buttons don't get squished in narrow containers (especially, but not exclusively, event comparisons on narrower screens).
The layout is unchanged if there's enough room, but on a narrow screen the buttons will automatically wrap to the next line and the search box will expand to take up its whole row.
