fix: add video driver capability so NVENC works in the container

The Go-Live broadcast encodes with h264_nvenc, but the image only requested
NVIDIA_DRIVER_CAPABILITIES=compute,utility. The NVIDIA Container Toolkit gates
which driver libraries it injects by capability, and the NVENC/NVDEC libs
(libnvidia-encode.so.1 / libnvidia-decode.so.1) come with the `video`
capability. Without it the broadcast ffmpeg dies with
"Cannot load libnvidia-encode.so.1", the capture produces no packets, and
Go-Live never connects, while CUDA workloads (ollama/whisper/melo) and
nvidia-smi keep working because compute+utility are present.

Add `video` so hardware encode is available. Applies to both Linux (CDI) and
Windows Docker Desktop (WSL2).
