How it works: explain Spending vs Savings for laymen

The one-paragraph section grows to three: the pocket-cash vs savings
analogy, what actually runs Spending (Ark's shared pool locked to your
key, plus Lightning interop) in plain words, and a rule of thumb for
which balance money belongs in. Also fixes the stale housekeeping
paragraph that still told users to refresh coins in Settings — that's
automatic now. Stale translations of the two changed keys are pruned so
locales fall back to the new English.

Your Spending balance sits in a shared pool coordinated by a coinos server, but every coin in it is locked to your key — the server can’t move a sat without your signature.

Behind the scenes this uses Ark and Lightning, but you never have to think about either.',
