Show actual bytes values instead of MB conversion

- Removed MB conversion in run_all.sh
- Now displays actual bytes values from memory profiling
- Updated output to show 'bytes avg / bytes peak'
- More accurate representation of memory usage
- Consistent with timeline data which is already in bytes
