fix(window): preserve maximized state when reactivating minimized window

Save window state before activation and skip saveWindowSize/moveToCenter
for maximized windows, restore showMaximized in fallback path.

保存窗口状态再激活，最大化窗口跳过 saveWindowSize 和 moveToCenter，
fallback 分支恢复 showMaximized。

Log: 修复最小化后再次打开丢失最大化状态的问题
PMS: BUG-355967
Influence: 修复最大化后最小化再打开窗口状态变为普通窗口的问题。
