// Explanation: If we have 1 USD = 0.9 EUR, then rates: { USD: 1, EUR: 0.9 } (assuming base is USD?).
// Actually, we store rates as: 1 unit of currency = rate units of base currency.
// Let's define: we have a base currency (e.g., USD) and rates are the value of 1 unit of that currency in base.

// value_in_base = value * rate[A]
// value_in_target = value_in_base / rate[B]
// So: result = value * (rate[A] / rate[B])
// However, note that in our ExchangeRateService, we store the rate as the amount of base currency per unit of the currency.
// For example, if base is USD, then rate for EUR is 0.9 (meaning 1 EUR = 0.9 USD).
// Then to convert 100 EUR to USD: 100 * 0.9 = 90 USD.
