sjg 815efdb1ae [fix](trx-backend-soapysdr): match sum/diff filters and simplify stereo blend
- Set STEREO_DIFF_BW_HZ = AUDIO_BW_HZ so both filter paths have
  identical group delay (improves multitone separation by ~10 dB).
- Zero out STEREO_SEPARATION_PHASE_TRIM (unnecessary with matched filters).
- Replace gradual blend ramp with binary blend: full stereo at pilot
  lock, mono when unlocked. The hysteresis thresholds already handle
  noisy signals.
