refactor(push_stream_anpviz.sh): optimize ffmpeg parameters for video streaming

- Updated ffmpeg command to remove audio stream and adjust video encoding settings.
- Set video resolution to 1280x720 and frame rate to 25 fps for improved performance.
- Removed Bearer Token as WHIP URL now includes authentication key, simplifying the script.
