fix: ProjectSearchBarDialog (search small screen) Suggestions once (#223)

Refactor the rendering logic of the suggestion list in `ProjectSearchBarDialog` component. This change simplifies the conditional rendering by restructuring the JSX to be more readable and maintainable. Now, the 'Suggestions' label is rendered once if there are items, and the items are mapped afterward.
