Detects when user changes same config setting 3+ times within 24 hours. Shows non-intrusive prompt offering help with guided calibration flow. Guided calibration features: - Test for false positives (walk around room) - Test for missed motion (sit still) - Suggest optimal value based on diurnal baseline SNR and link health - Apply suggested value button Files: - dashboard/js/proactive.js: Complete implementation with localStorage tracking Acceptance: - Help prompt fires after 3+ changes in 24h - Calibration flow tests both directions - Suggests value based on system data - Apply button works
