Assert in DFT Stereo gain encoder with -10 dB input and DEBUGGING enabled

Commit SHA: 0cd7d42d (Thu Nov 27 14:49:53 2025)

An assert is triggered in stereo_dft_quantize_res_gains for -10 dB input and DEBUGGING enabled. This

To reproduce, build with DEBUGGING enabled and run:

python3 tests/scale_pcm.py scripts/testv 0.3162

./IVAS_cod -max_band scripts/testv/ivas_bws_20fr_start_WB.txt -stereo -dtx 32000 48 scripts/testv/stvST48n.wav bs.192

Comes from this test case which is failing in the BASOP tests here: https://forge.3gpp.org/rep/sa4/audio/ivas-basop/-/jobs/646786
