Point of sale: a bill, an optional tip prompt, one invoice, and a ledger that keeps tips apart.

A new deferred feature (src/features/pos.js): type the amount in the display
unit, optionally a note, Charge. With the tip prompt on, the customer sees
the bill and picks a percentage (configurable, default 10/15/20), their own
figure, or no tip; one Lightning invoice is made for the total through the
Ark feature's receive (new hooks arkLnInvoice/arkLnWatch/arkLnUnwatch/
arkLnCancel wrap createLnInvoice and pollArkLn). Paid, expired and cancelled
sales are recorded with the bill and the tip as separate figures, and the
fiat rate at the time; the amount screen shows today's bills, tips and total.

Doors: Settings → Payments card, and a button under the payment address on
Receive (a receiveExtras hook the names pane renders).
