Add detailed debug logging for query performance tracking

Added comprehensive debug logging to track query performance:
- EventStore: Log filter details and duration for each query
- useAuthor: Log query duration and whether profile was found
- NostrProvider: Log event count from each relay

This will help identify where delays are occurring:
- Are queries fast but waiting for network?
- Is IndexedDB slow?
- Are profiles missing from cache?
