[Bug]: Missing Predictive Back animation

[kapatych-be]

Description

The app lacks the system "Predictive Back" animation. When performing the back gesture, the current screen does not scale down/shrink to reveal the previous one, which is a standard behavior for modern Android apps with Material You.

Steps to reproduce

Ensure the "Drag to Back" option is enabled in Chat Settings.
Navigate to any sub-menu (e.g., Data and Storage).
Perform a back gesture (swipe from the left or right edge).

Expected behavior

The system Predictive Back animation should be triggered, where the current activity/fragment scales down slightly before closing.

Actual behavior

The screen closes with a basic transition without the predictive scaling effect.
