Update visibility logic in ThreadedPost component

- Refined the visibility logic to ensure a post is only hidden if its parent is collapsed, rather than if it is collapsed itself. This change enhances the clarity of post visibility in threaded discussions.
- Adjusted the parent-collapsed prop to reflect the current collapse state, improving the interaction and user experience within the NostrFeed module.
