Bug: Redundant Focus Logic in AddAppButton

The AddAppButton component has redundant search input focus logic. The button's onClick handler uses setTimeout to focus the input, but this runs before the menu is rendered, creating a race condition. The Transition's afterEnter callback correctly focuses the input once the menu is visible, making the onClick handler unnecessary.
