debug: add detailed logging to fetchProfiles function

Add comprehensive logs prefixed with [fetch-profiles] to track:
- How many profiles are requested
- Cache lookup results
- Relay query configuration
- Each profile event as it's received
- Summary of fetched vs missing profiles
- Which profiles weren't found on relays

This will help diagnose why only 9/19 profiles are being returned.
