FeedbackWidget: custom styles prop replaces defaults instead of merging

[sbs44]

The styles prop on FeedbackWidget uses a shallow spread:

const styles: FeedbackWidgetStyles = { ...defaultStyles(theme), ...this.props.styles };

This means passing a partial override like styles={{ input: { color: 'red' } }} completely replaces the default input style object, losing all its other properties (height, padding, borderWidth, fontSize, etc.).

Expected: Custom style properties merge with defaults so unspecified properties are preserved.

Actual: The entire style object for that key is replaced, breaking layout.

Opened #5625 with a fix — replaces the shallow spread with a dynamic deep merge over all style keys.
