Video endpoints: use ffmpeg-full for drawtext, fix ARG_MAX via filter_complex_script

Browse Source 
- Added FFMPEG Lazy static + ffmpeg_cmd() with DYLD_LIBRARY_PATH
- Replaced bitmap font rendering with drawtext (1 filter vs 35 per letter)
- Large traces (>1000 detections) may still fail (ARG_MAX with -vf)
