feat(passes/radar): port pass history + compass calibration, cumulative what's new

- Pass history (Iu-yang1 fork): PassesSettings.hoursBefore look-back window;
  second 'Time before' slider in the pass filter; completed passes stay
  listed (progress clamped to [0,1]) in the history window.
- Compass calibration (Iu-yang1 fork): OtherSettings.compassOffsetDegrees,
  CompassAccuracy from the magnetic sensor, calibration dialog with
  figure-eight accuracy meter, corrected heading and manual offset field;
  RadarViewModel applies the offset.
- What's New dialog now shows the cumulative 4.4.6->4.4.7 changelog and
  follows the system language (values/ + values-zh/).
- pass_filter_history_hours localized in es/ru/si/tr/uk.
