fix: Update StreamVideo tests to handle process termination correctly

- Remove dependency on playground app for video streaming tests
- Handle SIGTERM (15) exit code which is expected when terminating the process
- Adjust data size expectations due to buffering limitations
- All StreamVideo tests now pass successfully
