feat: Enhance invoice item management with detailed line item structure

- Introduced nested interfaces for line items including customs, financials, quantities, descriptions, and references.
- Updated Item interface to include lines as an array of LineItem.
- Modified invoice top fields to handle pedimento ID and auto-assign values from the invoice.
- Enhanced item configuration component to manage line item properties and descriptions.
- Updated main data, packages section, summary section, and other components to bind new line item properties.
- Implemented normalization of numeric values when editing items to ensure consistent data types.
- Adjusted save invoice logic to accommodate new line item structure and compliance data.
