Add Code Formatting Configuration

[tesol2y090]

Problem

The project currently lacks consistent code formatting standards and automated tooling for maintaining code style. This makes it harder to maintain code consistency across the codebase and between different contributors.

Proposed Solution

Implement standardized code formatting using Prettier and ESLint with:

• Consistent formatting rules for TypeScript/React
• Integration with Tailwind CSS for class sorting
• No pre-commit hooks requirement for lighter development setup
• Simple npm scripts for formatting

Technical Requirements

• Add Prettier configuration
• Configure ESLint to work with Prettier
• Add format scripts to package.json
• Include Tailwind CSS class sorting
