fix: preview SQL popover not presenting from toolbar button (#740)

Move .popover() from the disabled Button to an always-enabled VStack
wrapper so SwiftUI can anchor the popover regardless of button state.
Also remove attachmentAnchor: .point(.bottom) which caused incorrect
positioning in macOS toolbars.
