Resolve DNS Failures & Normalize Shell Scripts in Docker Environment

[wahid18-maqs]

Fixes:

Summary

This PR includes the following changes:

• Adds DNS configuration (8.8.8.8, 1.1.1.1) for key Docker services (django-1, worker, worker_py3_8, nodejs, stats-exporter) in docker-compose.yml to resolve Temporary failure in name resolution.
• Adds .gitattributes with text=auto to normalize line endings and prevent platform-specific diffs.
• Adds base.txt to centralize and simplify Python dependency management across environments.

Motivation

• Fixes:
  • [Errno -3] Temporary failure in name resolution
  • /usr/bin/env: ‘bash\r’: No such file or directory
  • /usr/bin/env: use -[v]S to pass options in shebang lines
• Prevents CRLF-related script failures.
• Improves cross-environment consistency and maintainability of dependencies.

Testing Done

Verified DNS resolution inside containers using:

python -c "import socket; print(socket.gethostbyname('google.com'))"
