Upgrade project to React 19 and integrate new features

[justArale]

React 19 introduces several powerful improvements that can enhance our project's performance, maintainability, and developer experience. This issue tracks the migration and implementation of key React 19 features:

Planned Updates:

• useActionState for cleaner async handling

Simplifies form submission state management and validation.

• use() hook for direct async data fetching

Handles promises natively, eliminating unnecessary boilerplate.

• React Server Components for better SSR performance

Improves server-side rendering by sending lightweight results to the client.

• Enhanced asset loading with native lazy loading

Reduces load times and improves user experience.

Tasks:

• Upgrade dependencies to React 19.
• Refactor form handling using useActionState.
• Implement use() where applicable for async data fetching.
• Optimize server-side rendering with React Server Components.
• Ensure images and assets benefit from React 19’s native lazy loading.
