feat: redesign Bench page with Fluent card layout and radial advance monitor

Three-column layout replacing the old HMI grid:
- BenchRpmCommandCard: inline numeric input, 2×4 preset grid, Start/Stop
- BenchActuatorsCard: direction toggle, oil pump, temperature PID, misc relays
  with FluentStateToggle showing checked state via AccentFillColor
- BenchLiveDataCard: 2×5 KPI tiles (RPM, P1, P2, Q-Delivery, Q-Over, temps)
- BenchChartsCard: 2×2 compact chart grid (Delivery, Over, P1, P2)
- AdvanceMonitorCard: RadialAngleGauge custom FrameworkElement + PSG/INJ readouts,
  Δ° lock offset input, Zero PSG / Zero INJ buttons

Supporting changes:
- AngleDisplayViewModel: promote _currentManualDegrees, _isLockSet to
  [ObservableProperty]; add PsgRelativeDegrees, InjEncoderDegreesValue,
  TargetLockAngle, IsRunningMode (29/31 hysteresis); computed PrimaryGaugeAngle,
  TargetAngleForGauge, SecondaryGaugeAngle
- BenchControlViewModel: add IsDirectionLeft computed property,
  SetDirectionRightCommand, SetDirectionLeftCommand, ApplyRpmCommand
- FlowmeterChartView: add IsCompact DP (false default) for 90px compact height
- Styles.xaml: add IsChecked trigger to FluentStateToggle (accent fill + white text)
- Strings.en/es.xaml: add all new card and actuator string keys
