Frontend: Improve README structure

[Ayush8923]

Is your feature request related to a problem?
The current frontend README is poorly structured and lacks clear, step-by-step setup instructions. This complicates onboarding for new developers and creates confusion regarding the development workflow.

Describe the solution you'd like
Restructure and clean up the README with an organized format, including a Table of Contents and essential sections such as:

• 📋 Table of Contents
• Pre-requisite
• Software Dependencies
• npm (via asdf)
• Kaapi Backend
• Clone Frontend Repo
• Git commands to clone
• Installation
• Start backend server
• Start frontend server
• Available Scripts
• Localization
• Deploying Release on EC2 with CD
• Learn More

Each section should have clear explanations and step-by-step instructions where needed.
