Refactor IP copy functionality into a reusable component

Extracted the "Copy IP" button to a new `CopyIpComponent` to improve reusability and modularity. Updated `HomeComponent` to use this new component and removed redundant methods for copying text to the clipboard. Added tests and styles for the new component.
