fix(transcode): conditionally fix VAAPI filter order for HEVC (tested on Haswel) l

Browse source 
Places 'format=nv12' before 'hwupload' in the VAAPI video filter chain only when the input codec is HEVC and hardware decoding is disabled. This resolves filtergraph/driver issues observed on Intel Haswell GPUs when transcoding HEVC->H.264 VAAPI via software decode, ensuring the encoder receives the expected NV12 surface. Retains default filter logic for other codecs. Addresses issues discussed in GitHub issue
