fix(growing): switch to NVENC H.264 High Intra

Browse source 
Using libx264 confirmed raw2bmx works with AVC-Intra parameters at 59.94. Switching back to hardware-accelerated h264_nvenc with matching parameters (High profile, all-intra GOP 1, yuv422p, aud) to keep CPU load low during 8-port burn tests.
