Add copy-to-clipboard for version info

Allow long-pressing the version info row to copy the app version/build details to the clipboard and show a temporary confirmation toast. Adds UIKit import for UIPasteboard and haptic feedback, a showCopiedToast @State flag, contentShape to expand the gesture area, a 1.5s auto-dismiss animation for the toast, and a small UI label overlay with transition. This improves UX for sharing diagnostic/version information.
