Removes redundant "/api/v1" prefixes from API router definitions in the backend and updates the corresponding API calls in the frontend. This change streamlines the API structure and improves code maintainability. Additionally, adds console logs in the frontend to aid in debugging the API calls.
Extends expense entry functionality to support fiat currencies.
Users can now specify a currency (e.g., EUR, USD) when creating expense entries. The specified amount is converted to satoshis using exchange rates. The converted amount and currency information are stored in the journal entry metadata. Also adds an API endpoint to retrieve allowed currencies and updates the UI to allow currency selection when creating expense entries.
