[FIX] product_sale_price_from_pricelist: migrate data and add diagnostic tests

Migration (18.0.2.1.0):
- Migrate price fields from product.template to product.product
- Fields were previously stored in template during initial refactoring
- Data now properly located in product variant storage

Changes:
- Add migration pre-migrate.py to handle data migration automatically
- Add test_theoretical_price.py with comprehensive diagnostic tests
- Add test_full_flow_updates_theoretical_price to verify complete workflow
- Enhance stock_move.py with additional debug logging to diagnose issues
- Update __manifest__.py version to 18.0.2.1.0
- Update tests/__init__.py to include new test module

Fixes:
- last_purchase_price_received was stored in product.template but read from product.product
- Causes theoretical price calculation to show 0.0 instead of correct value
- Migration script copies data to correct model with company_dependent JSON format
