Fix NIP-17 inbox: fetch gift wraps from user's inbox relays

The subscribeToGiftWraps method was passing an empty relay array,
causing no gift wraps to be fetched. Now properly:
1. Fetches user's inbox relay list (kind 10050)
2. Subscribes to those relays for gift wrap events
3. Logs helpful warning if no inbox relays are configured
