feat: auto-scan 3-phase state machine with proper PD collection timing

- Phase 1 (waiting_fit): after sending control=0x01, wait for fitting=1
- Phase 2 (collecting): once fitting=1 AND run_state=1, start PD accumulation
- Phase 3 (done): run_state 1→0, calculate averages, auto-send treatment
- Check start-collecting in BOTH fitting and run_state handlers
- fitting=0 + run_state 1→0 = fitting failure, prompt retry
- Timeout 3 minutes (was 30s), auto-start treatment on completion
