[DOCS] Improve Code Documentation

[DeborahOlaboye]

Problem

Lack of documentation makes the codebase hard to understand and maintain.

Proposed Solution

1. Add JSDoc to all public APIs and components
2. Create/update README files for complex modules
3. Document component props and their types
4. Add examples for complex components

Acceptance Criteria

• 100% JSDoc coverage for public APIs
• All components have prop types and documentation
• Complex modules have README files
• Examples for all major components
• Update CONTRIBUTING.md with documentation standards
• Add TypeScript type definitions
