Greptile Summary

This PR fixes the Text Insertion Mode settings row so its description uses the available leading space and wraps vertically while preserving the picker's fixed width.

• Enables vertical wrapping for the mode description.
• Expands and leading-aligns the description container.
• Removes the redundant spacer between the description and picker.

Confidence Score: 5/5

The PR appears safe to merge, with the focused layout change preserving the fixed-width picker while allowing the description to wrap.

The modified row follows the established wrapping pattern used by sibling settings rows, and no concrete reachable layout failure remains.
