fix(auth-passkey): remove wordWrap to keep FIDO prompt single-line

[MyLeeJiEun]

问题

登录界面（greeter）切换到 FIDO 安全密钥认证后，提示文案跨两行显示；锁屏界面同一提示文案正常单行展示。

• Multica issue: DDE-97
• PMS: https://pms.uniontech.com/bug-view-370733.html

根因

AuthPasskey::initUI()（src/session-widgets/auth_passkey.cpp）中 m_textLabel->setWordWrap(true) 配合文本 label stretch=0（嵌在带双侧 stretch 的子布局中），使 QHBoxLayout 可将 label 压缩至低于整句宽度，触发换行。

greeter 与锁屏共用同一 AuthPasskey 组件，但运行环境的缩放/字体不同：greeter（约 1.5x 缩放）渲染使文本宽度超过换行阈值，锁屏（1.0x）未超过。其它认证模块（AuthFingerprint/AuthFace/AuthIris）因不设 wordWrap 或给 label stretch=1，不受影响。

改动

删除 AuthPasskey::initUI() 中 m_textLabel->setWordWrap(true); 一行，与 AuthFingerprint 保持一致。

     /* 文案提示 */
     m_textLabel->setText(tr("Please plug in the security key"));
-    m_textLabel->setWordWrap(true);

     /* 旋转提示和文案提示布局 */

移除 wordWrap 后，QLabel 的 minimumSizeHint() == sizeHint()（完整单行宽度），QHBoxLayout 无法再压缩该 label，两侧 stretch 自动让出空间，文案结构性保证单行展示——对 greeter 与锁屏均生效，锁屏无回归（由"碰巧不换行"变为"结构上不可换行"）。

验证

• 代码审核：通过（98 分）
• 编译打包：Qt6 编译通过，deb 包已构建（dde-session-shell 6.0.66）
• 未改动 greeter 字体设置（bug 161915 相关）及其它认证模块

说明

• GitHub master 分支为 v20/Qt5 变体，系统实际运行的 6.0.x 为 Qt6/snipe 变体，两者 auth_passkey.cpp 经验证完全一致（唯一差异即本次删除行），故直接在 master 分支提交。
• 本 PR 为 draft，待人工审核合并。

Summary by Sourcery

Keep passkey authentication prompts on a single line across authentication environments.

Bug Fixes:

• Prevent FIDO security-key authentication prompts from wrapping onto multiple lines in the greeter and lock screen.

Chores:

• Update the auth-passkey source copyright year range.

Hi @MyLeeJiEun. Thanks for your PR.

I'm waiting for a linuxdeepin member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Reviewer's Guide

Removes word wrapping on the FIDO/passkey prompt label so the layout structurally enforces a single-line message across greeter and lock screen, aligning behavior with other biometric auth widgets.

File-Level Changes

Change	Details	Files
Disable word wrapping on the FIDO security key prompt label to prevent layout-induced line breaks.	Removed the call that enabled word wrapping on the passkey prompt QLabel in the AuthPasskey UI initialization. Relied on QLabel’s single-line size hint so the HBox layout and surrounding stretches keep the prompt on a single line across different scaling/font environments. Kept behavior consistent with AuthFingerprint and other auth modules that do not enable wordWrap on their prompt labels.	src/session-widgets/auth_passkey.cpp
