App 2.17.0: speed average, compact top bar, About in Settings

- "Speed, 5-min average" card under Speed: time-weighted mean speed,
  standing included, from the same samples as the other averages.
- The top bar is one compact line (title and subtitle side by side).
  Version, update check and About moved from it to an App card on the
  Settings tab.
- The Overview no longer scrolls in the car's window: checked on the
  emulator at 1778x640, the layout height the car reports, after
  trimming the page's padding and the tyre card's height.
- The capacity hint says "Overview" instead of "Vehicle tab".
