App 2.13.0: tyre pressures in bar; 5-minute average power

Tyre pressures show in bar by default; Settings → Display offers kPa
and psi as well. Display only: the car reports kPa and the server keeps
storing kPa.

A "Power, 5-min average" card under Power: the time-weighted mean
battery power over the last five minutes, standing included, from the
same samples as the 5-minute range.
