Fix: Optimize tooltip positioning logic.

Log: The Popup is rendered on the window's Overlay layer and is not part of the content visual tree. As a result, the tooltip does not follow its anchor item during scrolling or window resizing, causing positional drift. To resolve this, AlertToolTip has been changed from a ToolTip (which uses Popup) to a regular Item, making it part of the content visual tree. This ensures it naturally scrolls with its parent, respects container clipping, and maintains correct positioning at all times.
