Bugfix: Stabilize Focused Text Input Scrolling

[fhasse95]

This PR stabilizes scrolling behavior for focused TextField and TextEditor views inside List and Table.

Before this change, the list item placement animation could continue running while a focused text input was inside the scrolling row. On Android/Compose, the focused text input layout can update independently from the surrounding LazyColumn item placement animation. Visually, this could make the focused TextField or TextEditor appear to lag behind the rest of the row while scrolling.

To reproduce:

1. Open a form-style List containing a TextField or TextEditor (e.g. the bottom text field in the FormPlayground of the Skip Showcase app).
2. Focus the text input so the cursor is active.
3. Scroll the list while the text input remains focused.
4. Observe that the focused input can visually lag behind the surrounding content.

Below is a before/after comparison of this example:

Before:

After:

As you can see, the focused text input now scrolls together with its row after this change.

I used Codex to iteratively investigate and refine the fix for the focused text input scrolling issue. To verify the results, I tested multiple playground views which contain text fields or text editors in the Skip Showcase app and my own Skip app. All of these scenarios work properly after the bug fix.
