[Notification Context]: collect of improves

**1. 'Clear All Notification' Animation**

#### Now
The "Clear All Notifications" button appears suddenly, without any animation.

#### To Do
Standardize the appearance of the 'Clear All Notification' button by introducing the same animation as used in other examples.

**2. Transition Consistency**
#### Now
Transition effects are inconsistent across different examples of notification context.

#### To Do
Implement a consistent transition effect of `.3s ease-in-out` for all examples of notification context to ensure a smoother visual experience.

**3. Notification Disappearance Order**

#### Now
Notifications disappear in an order different from their appearance when there are more than two notifications. The first notification that appeared is not the first to disappear.

#### To Do
Review and correct the disappearance order of notifications to ensure they vanish in the same order they appeared.
