Made two minimal, surgical fixes to stabilize ON/OFF splitting.

Browse Source 
What I changed

  - Core/Inc/main.h:76
      - Set ADC_BUFF_SIZE from 50 to 64 so each half is even (32). This keeps the “i &
        1” parity consistent across half-buffer boundaries.
  - Core/Src/stm32f4xx_it.c:388
      - Fixed N after splitting the first half: ADC_proc.N = (ADC_BUFF_SIZE/2 -
        Sweep_state.curr_step_start_DMA_N)/2;
      - Previously it used (Sweep_state.curr_step_start_DMA_N)/2, which was wrong for
        that segment.

  Why this helps

  - With ADC_BUFF_SIZE=50, half-size is 25 (odd). That flips ON/OFF labeling each half
    because i & 1 parity shifts by 25, mixing levels and driving avg_ON and avg_OFF
    together.
  - The N bug skewed normalization, further flattening differences between averages.

  How to verify

  - Build and flash: make && make flash.
  - Observe avg_ON/avg_OFF over CDC. They should now differ consistently; inverting
    meандр should swap them cleanly.
  - If still needed, I can add a global sample counter (sample_seq) for fully robust
    ON/OFF classification without relying on buffer indices.
