feat: implement MVP Phase 1 — full-area scan with ADC data collection

- Send scan command: all 5 regions LED on, brightness 128
- Listen for ADC notify (17 bytes) instead of broken queryStatus
- Parse and display PD1-PD7 values with visual bars
- Show VBAT/battery info
- Store scan PD data in globalData for Phase 3 smart adjustment
- 8s timeout fallback, stop LED on page unload
