Enhances Beancount import and API entry creation

Browse source 
Improves the Beancount import process to send SATS amounts with fiat metadata to the API, enabling automatic conversion to EUR-based postings.
Updates the API to store entries in Fava instead of the Castle DB, simplifying the JournalEntry creation process.
Adds error handling to the upload entry function.
Includes a note about imported transactions being stored in EUR with SATS in metadata.
