Subject: [PATCH] Update Cardsidebar.vue fix: Prevent TypeError crash on
 undefined currentCard

Adds optional chaining to `newCard.id` and `oldCard.id` in the watcher of `CardSidebar.vue`.

This prevents a UI crash (`TypeError: Cannot read properties of undefined (reading 'id')`) when the sidebar attempts to render a card that has been deleted or failed to load, causing `newCard` to be undefined.
