fix(editor): 右键粘贴含 CRLF 的剪贴板文本不再报选区越界 (#9576)

SQL 编辑器里选中一百多行后，右键“粘贴”从 Excel 复制的表格数据会报
“读取剪贴板失败：Selection points outside of document”，文档内容不变；
先删除文本再粘贴则正常。

右键粘贴按剪贴板原文长度计算光标位置，而 CodeMirror 会把插入文本中的
\r\n、\r 归一化为 \n，实际写入的文本比原文短，光标落到文档末尾之后，
dispatch 抛出 RangeError: Selection points outside of document。

- 新增 queryEditorClipboardPasteChange：先归一行尾再按实际插入长度计算光标
- QueryEditor 右键粘贴改用它，选区长度不再影响粘贴是否成功
