feat: add issued invoice detail page and related functionality

- Implemented IssuedInvoiceDetailPage component with loading and error states. - Created utility functions for building issued invoice detail actions and view models. - Added API adapter for fetching issued invoice details by ID. - Developed hooks for managing issued invoice queries. - Introduced new entities and types for issued invoices, including items, taxes, and recipient details. - Added tests for view models and API adapters to ensure correctness. - Organized code structure by creating separate files for components, utilities, and hooks.
