Closes #5762
Fixes #5490

如果不在主界面，则会在切换回主界面之后再显示；如果已经有对话框，则在对话框关闭后再显示

没测试过,因为太菜了不会在开发环境搞版本更新 : (

俺寻思能跑

Code Review

This pull request introduces a dialog queuing system to prevent overlapping UI elements, specifically for update notifications. It adds showLater functionality to DialogUtils and DecoratorController, allowing dialogs to be displayed sequentially. In MainPage, the update dialog logic was refactored to use this new system and bound to application state in Controllers. Feedback was provided regarding the use of identity comparison for RemoteVersion objects, suggesting Objects.equals() to ensure consistent behavior when checking for previously shown versions.

Code Review

This pull request introduces a dialog queuing mechanism to ensure that multiple dialogs are displayed sequentially rather than overlapping. It refactors the update notification logic in the main page to use this new 'show later' functionality and binds the update dialog's visibility to the application's navigation state. A review comment suggests adding a null check for the dialog action in DialogUtils to prevent potential null pointer exceptions.

[gemini-code-assist]

It is recommended to add a null check for showDialogAction before adding it to the queue to prevent potential NullPointerException when the action is eventually executed.
