Fix exchange rate parity across all document types

- Fix exchange-rate service types to match actual backend response shapes
  (exchangeRate array, activeProvider success/error, used currencies as strings)
- Add ExchangeRateConverter to payments, expenses, and recurring invoices
- Set currency_id from customer currency in invoice/estimate selectCustomer()
- Load globalStore.currencies in ExchangeRateConverter on mount
- Pass driver/key/driver_config params to getSupportedCurrencies in provider modal
- Fix OpenExchangeRateDriver validateConnection to use base=USD (free plan compat)
- Fix checkActiveCurrencies SQLite whereJsonContains with array values
- Remove broken currency/companyCurrency props from ExpenseCreateView, use stores
- Show base currency equivalent in document line items and totals when exchange
  rate is active
