Improve the audio bus editor appearance

- Use the editor font color for notch lines and text instead of a more
  contrasted color.
- Reuse the editor theme's tooltip styling and apply it on theme change.
- Make the preview label display an explicit `+` sign for positive values.
- Prevent a zero value from displaying as `-0.0 dB` instead of `0.0 dB`.
- Scale notch lines on hiDPI displays.
