fix(sample): dismiss bottom sheet before launching file picker on iOS

iOS cannot present a UIDocumentPickerViewController while a
ModalBottomSheet is still visible (stacked modals not supported).

Use a pendingPick flag + LaunchedEffect to launch the picker only
after the sheet is fully dismissed. Also revert the unnecessary
security-scoped resource access changes in VideoPlayerState.
