debug: add comprehensive logging for profile loading states and article refresh

- Add logs to useProfileLabels for loading state tracking
- Add logs to markdown processing to track when content is cleared/reprocessed
- Add logs to article loader for refresh behavior
- Add logs to ResolvedMention and NostrMentionLink for loading detection
- Add logs to nostr URI resolver when loading state is shown
- All logs prefixed with meaningful tags for easy filtering
