refactor(phone-image): wangeditor 排版引擎核心重构

Browse Source 
- 两栏布局：取消左侧工具栏，中间改为wangeditor v5编辑器
- 顶部操作栏：设置/保存/生成并保存+更多下拉(历史/重新生成/下载/长图)
- 设置弹框：尺寸选择+水印输入，删除全局字号滑块
- wangeditor完整工具栏+divider分割线标记分页
- 删除旧渲染管线：renderContentFlow/insertPageBreak/removePageBreak/convertFlowBlocksToImages/measureBlockHeights
- 新增captureEditorBlocks：从编辑器DOM测高+按分割线分组+实际高度分页
- 新增exportLongImage：从wangeditor DOM截长图
- getContentHtml改为从wangeditor实例读取
