Subject: [PATCH] Fix Neo4j query returning zero events for REQ filters
 (v0.49.1)

- Fix zero-value timestamp filter bug: since/until with value 0 were
  being added as WHERE clauses, causing queries to match no events
- Fix event parsing: use direct slice assignment instead of copy() on
  nil slices for ID, Pubkey, and Sig fields

Files modified:
- pkg/neo4j/query-events.go: Fix buildCypherQuery and parseEventsFromResult
