[GEN-2041]: fix auto-fill indicator for destinations

[BenElferink]

This pull request includes several updates to the frontend/webapp/containers/main/destinations directory, focusing on enhancing the DestinationFormBody component and improving the export structure of the DestinationsList component. The most important changes include adding new hooks and logic to handle auto-filling of dynamic fields, modifying the component structure for consistency, and updating export statements.

Enhancements to DestinationFormBody component:

• Added useEffect and useRef hooks to handle the auto-filling check for dynamic fields and set the autoFilled state accordingly. [1] [2]
• Modified the DestinationFormBody component to be a functional component using arrow function syntax for consistency. [1] [2]
• Updated the rendering logic to display a notification note when the connection details are auto-filled.

Improvements to DestinationsList component:

• Changed the DestinationsList component to be exported directly instead of using a separate export statement. [1] [2]
