Pull Request Overview

This PR migrates the contract_sii module from a previous version to Odoo 18.0, adding SII (Spanish tax system) integration capabilities to contracts. The module allows contracts to include SII registration keys and property information that propagates to generated invoices.

Key changes include:

• Complete module structure for SII contract functionality
• Model extension for contract.contract with SII fields and invoice preparation logic
• View form integration showing SII fields based on contract type and registration key
• Comprehensive test suite covering both sale and purchase contract scenarios
