Enhance PatientLandingPage for Maintainability and Scalability

[itspavant]

📌 Description

The current PatientLandingPage dashboard works but lacks scalability, security, and code clarity.
There are opportunities to improve readability, implement functional logout, and make it beginner-friendly for contributors.

✅ Proposed Changes

• Implement secure logout by clearing localStorage and sensitive info.
• Refactor code for better readability and maintainability.
• Add inline comments and docstrings to help new contributors understand the component structure.
• Modularize the dashboard cards for scalability (e.g., dynamic generation of menu options).
• Ensure responsive styling consistency using PatientLanding.module.css.
• Optional: Add unit tests for component behavior (welcome message, logout, navigation).

🚀 Benefits

• Makes the dashboard secure, scalable, and maintainable.
• Easier for GSSoC’25 contributors to onboard and extend the dashboard.
• Improves code quality and best practices across the project.
• Provides a professional, beginner-friendly open-source contribution opportunity.
