fix: add AT-SPI accessible names for missing widget classes

[re2zero]

Summary

Add setAccessibleName() calls and register missing widget classes in the accessible factory to improve AT-SPI / accessibility coverage.

Changes

accessible.h — New widget registrations

• TitleMenu, FindWidget, SlidePlayWidget, FileAttrWidget: New SET_FORM_ACCESSIBLE entries
• SideBarImageListView, CatalogTreeView: DListView/DTreeView subclasses
• HandleMenu, ScaleMenu, BrowserMenu: DMenu subclasses
• QTextEdit: SET_EDITABLE_ACCESSIBLE generic registration
• DFloatingWidget, DMenu, DAbstractDialog, DListView, DTreeView: Generic DTK base types
• Fixed missing USE_ACCESSIBLE for DLabel and DToolButton

setAccessibleName() additions

• SlidePlayWidget: widget + buttons (previous_normal/play_normal/next_normal/exit_normal)
• TransparentTextEdit: widget itself
• HandleMenu, ScaleMenu: menu widgets
• FileAttrWidget, FindWidget: dialog/widget names
• SideBarImageListView, CatalogTreeView: list/tree controls
• SlideWidget: slideshow widget
• ScaleWidget: widget + zoom in/out buttons + scale menu button
• CentralDocPage: tab label
• DocSheet::LoadingWidget: loading indicator
• EncryptionPage: icon label, info label, password edit
• SecurityDialog: title/content labels

AT-SPI coverage improvement

• Before: ~25% of custom widget classes were unregistered in the accessible factory
• After: All Qt/DTK widget subclasses now have proper accessible entries

Summary by Sourcery

Improve accessibility coverage by registering previously missing widgets in the accessibility factory and assigning accessible names to key UI components.

Enhancements:

• Register additional custom Qt and DTK widget subclasses (menus, dialogs, lists, trees, floating widgets) with AT-SPI accessibility mappings.
• Enable QTextEdit and core DTK base types to participate in the generic accessibility infrastructure.
• Assign explicit accessible names to dialogs, widgets, labels, buttons, spinners, and password fields in reader UI screens to improve screen reader usability.

Reviewer's Guide

Registers previously-uncovered custom Qt/DTK widgets in the accessibility factory and assigns explicit accessible names to key widgets and controls, improving AT-SPI coverage and screen reader labeling across the reader UI.

File-Level Changes

Change	Details	Files
Register missing custom widgets and base DTK/Qt classes in the accessibility factory so they expose QAccessible interfaces.	Include headers for additional widget classes (e.g., FindWidget, SlidePlayWidget, FileAttrWidget, TransparentTextEdit, SideBarImageListView, CatalogTreeView, HandleMenu, ScaleMenu, BrowserMenu). Add SET_FORM_ACCESSIBLE/SET_EDITABLE_ACCESSIBLE entries for new custom widgets and base classes, including QTextEdit and several DTK base widgets (DFloatingWidget, DMenu, DAbstractDialog, DListView, DTreeView). Add corresponding USE_ACCESSIBLE mappings in accessibleFactory() for the new custom widgets and DTK/Qt base classes, and ensure DLabel and DToolButton now use accessibility implementations.	reader/app/accessible.h
Assign explicit accessible names to key widgets and child controls to improve screen reader descriptions.	Set accessible names on container widgets such as ScaleWidget, SlidePlayWidget, SlideWidget, FileAttrWidget, FindWidget, HandleMenu, ScaleMenu, SecurityDialog, CatalogTreeView, SideBarImageListView, CentralDocPage tab label, TransparentTextEdit, and DocSheet::LoadingWidget. Set accessible names for child controls like zoom buttons and scale menu button in ScaleWidget, slide control buttons in SlidePlayWidget, SecurityDialog title/content labels, EncryptionPage icon and info labels and password edit, and the loading spinner in DocSheet::LoadingWidget.	reader/widgets/ScaleWidget.cpp reader/widgets/SecurityDialog.cpp reader/widgets/EncryptionPage.cpp reader/uiframe/DocSheet.cpp reader/widgets/SlidePlayWidget.cpp reader/sidebar/CatalogTreeView.cpp reader/sidebar/SideBarImageListview.cpp reader/uiframe/CentralDocPage.cpp reader/widgets/FileAttrWidget.cpp reader/widgets/FindWidget.cpp reader/widgets/HandleMenu.cpp reader/widgets/ScaleMenu.cpp reader/widgets/SlideWidget.cpp reader/widgets/TransparentTextEdit.cpp

❌ 本地验证失败（编译错误）

已在本地子项目 deepin-reader 完成 cherry-pick + 代码 review + dpkg 编译验证：

• Cherry-pick: 干净（15 文件，+70/-2，无冲突）
• 代码 Review: FAIL —— 发现会导致编译失败的硬错误
• 编译: dpkg-buildpackage -us -uc -b -tc -j$(nproc) 失败（exit 2，约 96% 进度处）

致命错误：reader/app/accessible.h:93 新增 SET_EDITABLE_ACCESSIBLE(QTextEdit, ...)，宏展开生成 return m_w->text();，但 QTextEdit 没有 text() 成员（只有 toPlainText()/toHtml()）：

reader/app/accessibledefine.h:143:21: error: 'class QTextEdit' has no member named 'text'
  143 |         return m_w->text(); \

修复建议：将 FUNC_TEXT_ 宏对 QTextEdit 的处理改为 toPlainText()（或对 QTextEdit 单独定义 text() 实现）。

✅ 其余改动（9 个 SET_FORM_ACCESSIBLE 类、setAccessibleName() 调用、新增 include）均已核实无误，无无关文件误改、无版权/dep5 问题。修复该错误后即可编译通过。
