WattRamp v1.5.6

What's Changed

FTP Calculation Accuracy

• Coefficients respect user settings: FTP Prediction, Max Power, and RampTest fallback now use the selected calculation method (Conservative/Standard/Aggressive) instead of hardcoded Standard coefficients
• Added ftpCalcMethod to TestState.Running: All data fields can now access the user's FTP calculation preference in real-time

Data Field Consistency

• DeviationDataType: Zone status (IN ZONE / TOO LOW / TOO HIGH) now uses dynamic zoneTolerance from settings via isInTargetZone, consistent with PowerZoneDataType. Previously used hardcoded ±10W threshold causing conflicting zone indicators
• CurrentIntervalDataType: Added division-by-zero guard for interval progress calculation

TestEngine Accuracy

• Max 1-minute power fixed: Rolling window threshold changed from 30 to 60 samples. Previously reported inflated max 30-second average as "max 1-minute power", affecting FTP Prediction display during Ramp tests
• Elapsed time safety: getElapsedTimeMs() now clamped to non-negative values to prevent edge cases with system clock changes

Alert Improvements

• Test start double-beep: TESTING and TESTING_2 phases now trigger distinctive double-beep sound pattern (ALERT_GO) instead of generic single beep. Previously ALERT_GO was unused dead code
