Enhance invoice processing logic for IMD and Mexican purchases

- Updated validation logic to restrict 'IMD' document type usage unless the invoice type is 'DEF'.
- Refactored value assignment in the main processing flow to handle 'DEF' and 'MEX' invoice types with specific IVA calculations.
- Added logging for invoice processing to improve traceability and debugging.

These changes improve the accuracy of invoice validations and processing for specific document types.
