feat(decks): iOS-26 tabViewBottomAccessory für „Neues Deck"-Pille
Ersetzt den bottomBar-„+"-Button auf iOS 26 durch eine schwebende Liquid-Glass-Pille via `.tabViewBottomAccessory`, nur sichtbar wenn der Decks-Tab aktiv ist. iOS 18-Geräte behalten den bestehenden bottomBar-Button (gated via `if #unavailable(iOS 26.0)`). `showCreate` wandert als Binding von DeckListView nach RootView, damit das Accessory den Sheet triggern kann.
