feat: refactor app structure and components for improved organization and functionality

- Moved components and hooks into a new directory structure under `src/app` for better organization.
- Updated the main entry point to use `index.ts` and adjusted routing accordingly.
- Introduced new components such as `ActiveProcesses`, `AgentStreamView`, and `ConnectionStatus` to enhance the app's functionality.
- Removed deprecated components and hooks to streamline the codebase.
- Updated styles to align with the new theme structure and ensure consistency across the app.

This refactor aims to improve maintainability and scalability of the application.
