Add ESLint to Angular Project for Code Quality and Consistency

[mahmoodalisha]

ESLint will apply Angular's recommended practices for both TypeScript and HTML files, helping to stay aligned with Angular's guidelines and reducing the chances of introducing issues due to improper coding patterns. Running ESLint as part of development workflow will automatically detect potential issues, errors, and bad practices early on, allowing us to fix them before they become larger problems. This will ensure better code quality and fewer bugs in the long run.
