When `p2pAllowOnlyValidators` is enabled, unauthenticated peers were excluded from gossipsub, but could still freely query block data and transactions through req/resp protocols (BLOCK, BLOCK_TXS, TX) with no authentication check. This adds an authentication gate in `ReqResp.streamHandler()` that rejects unauthenticated peers on all protocols except those needed for the handshake flow (PING, STATUS, AUTH, GOODBYE) Ref: A-698
