Services followed configuration detection order, so frequently used services could not be kept together. Services can now be dragged before or after a sibling, with an insertion indicator and edge scrolling, or moved with Move Up/Down from the toolbar and context menu.
The order is stored per project location and type, separately from configuration definitions. New configurations append, windows stay in sync, and a failed save keeps the order for the session with a warning. Sorting in Tree is opt-in, so other trees are unchanged.
