Subject: [PATCH] fix(lockscreen): prevent window interaction on secondary
 screens while locked
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Set Greeter visible to true so it covers all outputs with MouseArea,
preventing interaction with windows on secondary screens. LockView and
ShutdownView are wrapped in a Loader with the original primary‑output
condition, keeping them instantiated only on the primary display.

将 Greeter 的 visible 设为 true 使其覆盖所有输出并拦截输入；
LockView 和 ShutdownView 通过 Loader 仅在主屏加载，修复多屏锁屏
时副屏窗口仍可操作的问题。

Log: 修复多屏锁屏副屏可操作的问题
PMS: BUG-367461
Influence: 锁屏状态下副屏不再有可交互的锁屏界面，输入被正确拦截。
