v1.4.2: show Fuliza reading date + stale-data hint

The Fuliza card showed a bare outstanding figure with no recency, so a
stale reading (e.g. an old full-clear at 0) looked current. It now shows
'as of <date>' and, when the latest Fuliza SMS is over a day old, prompts
re-running Import SMS history — Safaricom moved Fuliza to a dedicated
sender, so older messages need a one-time re-import to be read in.
