🔍 Key Features:

Field Focus: Converts the annual_budget field based on the currency specified in budget_currency.
Validation: Ensures both the currency code and amount are valid before proceeding.
Currency Check: If the currency is already USD, it bypasses conversion.
Exchange Rate Lookup: Retrieves the most recent exchange rates for both the source currency and USD.
Conversion Logic: Applies the formula
USD Amount=(Original AmountSource Rate)×USD Rate\text{USD Amount} = \left(\frac{\text{Original Amount}}{\text{Source Rate}}\right) \times \text{USD Rate}USD Amount=(Source RateOriginal Amount​)×USD Rate
Error Handling: Clears the USD field if any required data is missing or invalid.
