fix: correct scroll position when insert text on Android

[IvanIhnatsiuk]

Summary

This pull request improves the behavior of scrolling and style manipulation in the enriched text input component. The main focus is on ensuring the scroll position is updated correctly when paragraph styles are changed, and on making scrolling behavior more consistent and predictable. Additionally, there are some code quality improvements for better encapsulation and clarity.

Scroll and Layout Behavior Improvements:

• Introduced the correctScrollPositionIfNeeded() method in EnrichedTextInputView, which ensures the view scrolls to the correct position after certain style changes or text updates. This method is now called after removing or toggling paragraph styles and after text changes.
• Updated canScrollVertically and canScrollHorizontally to also check the superclass's scrollability, not just the scrollEnabled flag, for more accurate scrolling behavior.

Code Quality and Encapsulation:

• Changed the visibility of the view property in EnrichedStyleManipulator from val (public) to private to better encapsulate internal state.

Pull request overview

This PR improves Android scroll behavior in EnrichedTextInputView so the caret remains correctly visible after text mutations and certain style operations, addressing incorrect scroll position when inserting text / manipulating paragraph styles.

Changes:

• Added correctScrollPositionIfNeeded() to centralize “scroll-to-selection” correction and invoked it after text changes and paragraph style operations.
• Refined canScrollVertically / canScrollHorizontally to respect both scrollEnabled and the superclass’ actual scrollability.
