[PM-34833] bug: Search improvements

[gabrbrand]

📔 Objective

Improvements to the search experience:

• Show search icon only when content is displayed. Hidden when content is loading, there is an error or there are no items.
• Hide clear icon when search term is empty. (Animated)
• Use a formatted search string instead of hard coding the order. e.g. in German the words are in a different order
