Update ESLint and Snyk scripts to suppress error output and improve logging

- Modified run_eslint.sh and run_snyk.sh to redirect error output to /dev/null, enhancing log cleanliness.
- Ensured that failure messages are still logged to the main log file for transparency, while minimizing clutter during report generation.
