Implements a background task that listens for paid invoices
and automatically records them in the accounting system. This
ensures payments are captured even if the user closes their
browser before the client-side polling detects the payment.
Introduces a new `get_journal_entry_by_reference` function to
improve idempotency when recording payments.
Removes the `castle.` prefix from database table names in queries, streamlining data access.
Updates authentication to use `WalletTypeInfo` dependency injection for retrieving wallet information. This improves security and aligns with LNBits' authentication patterns. Also modifies the main router's tag to uppercase.
