    fix(loadbalance): prevent panic in consistent hash toKey for non-string 
args (#3430)
    
    The hard type assertion args[i].(string) panics for any non-string
    argument (int, struct, etc.), while Java Dubbo uses toString() which
    never fails. Replace with fmt.Fprint(&sb, args[i]) which safely
    converts any type to its string representation.
