Fix #19323: Resolve deck description dialog shaking

[Ayush-Patel-56]

Purpose / Description

Fixes a visual glitch where the deck description dialog would shake or jitter when adding new lines. The issue was caused by a circular layout dependency between the TextInputLayout and its child TextInputEditText.

Fixes

• Fixes Deck description dialog shakes sometimes #19323

Approach

The TextInputLayout was set to wrap_content (calculating height based on children), while its child TextInputEditText was set to match_parent (calculating height based on parent). This created a conflict where the layout engine struggled to resolve the height during content updates (like adding newlines), causing the "shaking".

I changed the android:layout_height of the TextInputEditText to wrap_content. This breaks the circular dependency, allowing the text input to grow naturally with its content, which the parent container then correctly wraps.

How Has This Been Tested?

manually tested on an Android Virtual Device (AVD):

1. Open the Deck Description dialog.
2. Add text and insert multiple new lines.
3. Verified that the dialog expands smoothly without shaking.

Thanks for the video, that was helpful. The previous attempt to just fix the dimensions within the NestedScrollView was clearly insufficient as the resizing loop persisted.

I have now completely refactored the layout to use a ConstraintLayout.

Changes:

• Static Layout: Replaced the NestedScrollView (which was causing the dynamic resizing/shaking loop) with a ConstraintLayout.
• Fixed-height Input: The TextInputLayout is constrained to fill the remaining space between the toolbar and the bottom options (0dp height). This forces the input field to remain a static size regardless of content.
• Internal Scrolling: The TextInputEditText now handles its own vertical scrolling internally within these fixed bounds, which completely eliminates the shaking behavior.

I've tested this and it results in a solid UI that doesn't shake when editing lines.
