Gate the peer-sync fast path on a runtime flag polled from Redis so operators can roll the optimisation out gradually and flip it off without a redeploy. Without NB_PEER_SYNC_REDIS_ADDRESS the routine stays disabled, every Sync runs the full network map path, and no entries accumulate in the peer serial cache — bit-for-bit identical to the pre-fast-path behaviour. When the env var is set, a background goroutine polls the configured key (default "peerSyncFastPath") every minute; values "1" or "true" enable the fast path, anything else disables it. - RunFastPathFlagRoutine mirrors shared/logleveloverrider: dedicated Redis connection, background ticker, redis.Nil treated as disabled. - NewServer takes the flag handle; tryFastPathSync and the recordPeerSyncEntry helpers short-circuit when Enabled() is false. - invalidatePeerSyncEntry still runs on Login regardless of flag state. - NewFastPathFlag(bool) exposed for tests and callers that need to force a state without going through Redis.
