⚠️ Merge order: the design-system PR should merge first.

Description:

The shared Search component (common/input/filter.search.js) routed its extraClasses prop through extraAria.className, which lands on the raw <input> and — due to spread order in the DS BaseInput — replaced the ids-input* classes entirely. With the default extraClasses = '' (the Image library case) the input rendered as <input class="">, i.e. completely unstyled.

extraClasses is now passed to InputTextInput's className prop (the .ids-input-text wrapper), matching the established pattern in top.menu.search.input.js.

Consumers checked: image-picker passes no extraClasses; segmentation passes c-segments__sidebar-filter, which has no SCSS/JS references anywhere in that package, so moving the class from the input to the wrapper changes nothing visually.

For QA:

1. Create/edit content with an image assets field → Select from library → the search input in the Image library header must be styled like other DS inputs (border, 40px height, magnifier button inside).
2. Regression: UDW top-menu search (browse tab), dropdown/popup-menu filter inputs — unchanged.
3. Page Builder → block targeting (segmentation) sidebar segment filter — unchanged.
