Offline keeps the classic wallet layout

Offline mode forces the settings tab, and the full-page settings layout
was hiding the balance card and tab strip there — walling an offline
user off from their cached balance, history, and the Savings receive
address. Offline now keeps balance + tabs around the settings content.
