fix(swarm,timeline): Include node NSFW status in post filtering

- Add node NSFW status check to post filtering logic
- Filter posts where either the post itself or its parent node is marked NSFW
- Ensure comprehensive NSFW content filtering across both post and node levels
- Prevents NSFW content from NSFW nodes from appearing in filtered timelines
