LNbits already stores what is needed on every payment's extra:

{ "fiat_currency": "EUR", "fiat_amount": 5.5, "fiat_rate": 1326.36 }

That is present for any payment created with a fiat unit, and also for outgoing LNURL payments sent with one.

Work

Carry fiatAmount / fiatCurrency through mapPaymentToTransaction onto PaymentTransaction.
Render the fiat amount as the primary figure with sats secondary, matching how #166 presents the created invoice. formatCurrency from useCurrencies handles locale and symbol.
Leave rows without a fiat denomination exactly as they are.

Why it was not in #166

It applies to all payments rather than only newly created ones, and it edits the shared payment mapper that #161 rewrites. Keeping it separate avoided a conflict between the two.

Worth considering at the same time: an optional "show amounts in my preferred currency" display setting, converting sat-denominated rows at the current rate. That is a different feature from recording the denomination a payment was actually quoted in, and should not be conflated with it.

Follow-up to #166, which lets an invoice be denominated in fiat. The history list still shows sats only, so a €5.50 invoice appears as "7,301 sats" and the quote the payer actually agreed to is lost.
