fix: copy bSubcodecMode in ParamTranscode so encoder context sees the flag

Isaac · claude · Isaac · commit 28608194a98a · 2026-04-07T08:49:45.000+02:00
Without this, SWelsSvcCodingParam::ParamTranscode was not copying
bSubcodecMode from SEncParamExt, so the encoder's internal pSvcParam
always had bSubcodecMode=false regardless of what the caller set.
