refactor(notification): move wayland guard into initScreenLockedState

1. Moved the Wayland platform check from the constructor into initScreenLockedState()
2. Replaced QGuiApplication::platformName() string comparison with DGuiApplicationHelper::testAttribute(IsWaylandPlatform)
3. Added TODO note for future Wayland session support in screen lock detection

Log: Refactor Wayland session check into initScreenLockedState using Dtk API

refactor(notification): 将 Wayland 检测移入 initScreenLockedState

1. 将 Wayland 平台检测从构造函数移入 initScreenLockedState() 方法
2. 使用 DGuiApplicationHelper::testAttribute(IsWaylandPlatform) 替代 QGuiApplication::platformName() 字符串比较
3. 添加 TODO 注释记录待 Wayland 支持屏幕锁检测

Log: 用 Dtk API 重构 Wayland 检测逻辑，移入 initScreenLockedState
