Issue: Optimize Authentication Controller for Clean and Efficient Code

[akofficial10]

📋 Description

The current authentication controller (authController.js) is functional but can be optimized for better readability, maintainability, and consistency without changing any existing logic or features.

✅ Expected Outcome

• Improve variable naming consistency (existing → existingUser, etc.).
• Enhance input normalization logic for clarity.
• Add consistent return statements for responses.
• Clean up comments and error messages.
• Preserve full functionality of registration and login.

💡 Proposed Solution

Refactor the file to:

• Use early returns for cleaner flow.
• Make helper functions more robust.
• Maintain all existing routes and functionality.
