fix: replace subscribeMany with querySync for nostr-tools v2 compatibility

The server was using the nostr-tools v1 API (subscribeMany with onevent/oneose
callbacks) but the installed version is v2.23.5 which changed the internal
subscription handling. querySync() is the correct v2 API for one-shot queries
and handles EOSE cleanly without needing manual timeout management.
