fix(server): correct RSSI/noise_floor byte offsets in frame parser (#332 )

The server parsed rssi from buf[14] and noise_floor from buf[15], but
the firmware (csi_collector.c) packs them at buf[16] and buf[17]:

  Firmware:  n_subcarriers=u16(6-7) freq=u32(8-11) seq=u32(12-15) rssi=i8(16)
  Server:    n_subcarriers=u8(6)    freq=u16(8-9)  seq=u32(10-13) rssi=i8(14) ← WRONG

This caused RSSI to read the high byte of the sequence counter instead
of the actual signed RSSI value, producing positive values (e.g., +9)
instead of the correct negative values (e.g., -46 dBm).

Added inline documentation of the frame layout matching csi_collector.c.

Closes #332
