fix: add streaming callback to relay list service for faster results

- Add onEvent streaming callback to relayListService queryEvents call
- Process events as they arrive instead of waiting for all relays to respond
- Deduplicate events by id and keep most recent version
- Remove artificial delay since streaming provides immediate results
- Should resolve hanging issue where debug works but app query hangs
