The "Return to previous board" button no longer crashes when a user encounters an "This board or ticket is unavailable" screen. Previously, the button would immediately request the user's first board from the server, causing a crash. Now it safely handles the unavailable state and prevents the error.
Added: The button now gracefully handles board unavailability scenarios and fails safely.
Fixed: Browser crash on board navigation errors.
