Refactor invoice status handling to use 'processed' terminology

- Renamed instances of 'invoice_updated' to 'invoice_processed' across various modules to improve clarity and consistency in invoice status management.
- Updated validation and processing logic to reflect the new terminology, ensuring that all references are aligned with the recent changes in the invoice processing model.
- Adjusted related functions and validation checks to maintain functionality and accuracy in invoice processing workflows.
