App 2.5.0: range estimates from current and 5-minute average power

The Vehicle tab gets two tiles next to the car's own range:

- Range at current power: remaining energy / (power / speed) right now.
- Range at 5-min average: remaining energy / (energy used / distance
  driven) over the last 5 minutes, integrated time-weighted from both
  the service tick (15 s) and the open screen (2 s), so it is ready as
  soon as the app opens.

Each shows the consumption it is based on (kWh/100 km). Remaining
energy is SOC x usable capacity, because the car publishes no pack
energy; the capacity is a new setting in the Consumption tab (default
50.8 kWh, the 51 kWh battery). Estimates read "—" with the reason when
they cannot mean anything: standing still, regenerating, too little
driving, or across a gap in the samples; over 999 km shows "> 999 km".

RangeEstimator is Android-free and has 7 tests. Also fixes the battery
card's note, which still said the SoH goes to MongoDB.
