SQLSelect — AddHaving passes wrong argument order

SQLSelect: correct AddHaving argument order
- Component: `src/ClassModules/SQLSelect.cls` (around 71–95)

### Problem
- Calls `SQLCondition.Create` with `(Field, op, Value)` but signature is `(Expression1, Expression2, Operator)`.

### Snippet (actual)
```vb
NewHaving.Create Field, op, Value
```

### Expected
```vb
NewHaving.Create Field, Value, op
```

### Steps to Reproduce
1) Add a HAVING with a non-default operator.

### Actual
- Generates the comparison with swapped operands/operator.

### Proposed Fix
- Pass `(Field, Value, op)` consistently in both branches.

打开 src/ClassModules/SQLSelect.cls 的第 71–95 行附近，检查两个分支中的 AddHaving，从调用 SQLCondition.Create 的地方开始。复现一个使用非默认运算符的 HAVING，并验证两个分支生成的比较具有预期的参数顺序。
