Add proper relay hints for fetching Zapstore releases

Use useLiveTimeline instead of eventStore.timeline() to actually fetch
release events from relays. Relay selection includes:
- Seen relays (where the app event was received from)
- Publisher's outbox relays (NIP-65)
- Aggregator relays as fallback

This ensures releases are properly fetched rather than just read from
the local event store cache.
