[ADD] website_sale_aplicoop: Phase 3 test suite implementation

Implementa test_phase3_confirm_eskaera.py con cobertura completa de los 3 helpers
creados en Phase 3 del refactoring de confirm_eskaera():

Helper Methods Tested:
- _validate_confirm_json(): Validación de request JSON
- _process_cart_items(): Procesamiento de items del carrito
- _build_confirmation_message(): Construcción de mensajes localizados

Test Coverage:
- 4 test classes
- 24 test methods
- 61 assertions

Test Breakdown:
1. TestValidateConfirmJson (5 tests):
   - Validación exitosa de datos JSON
   - Manejo de error: order_id faltante
   - Manejo de error: order no existe
   - Manejo de error: carrito vacío
   - Validación de flag is_delivery

2. TestProcessCartItems (5 tests):
   - Procesamiento exitoso de items
   - Fallback a list_price cuando price=0
   - Skip de productos inválidos
   - Error cuando no quedan items válidos
   - Traducción de nombres de productos

3. TestBuildConfirmationMessage (11 tests):
   - Mensaje de confirmación para pickup
   - Mensaje de confirmación para delivery
   - Manejo cuando no hay fechas
   - Formato de fecha DD/MM/YYYY
   - Soporte multi-idioma: ES, EU, CA, GL, PT, FR, IT

4. TestConfirmEskaera_Integration (3 tests):
   - Flujo completo para pickup order
   - Flujo completo para delivery order
   - Actualización de draft existente

Features Validated:
✅ Validación robusta de request JSON con mensajes de error claros
✅ Procesamiento de items con manejo de errores y fallbacks
✅ Construcción de mensajes con soporte para 7 idiomas
✅ Diferenciación pickup vs delivery con fechas correctas
✅ Integración completa end-to-end del flujo confirm_eskaera

Quality Checks:
✅ Sintaxis Python válida
✅ Pre-commit hooks: black, isort, flake8, pylint (all passed)
✅ 671 líneas de código de tests
✅ 29 docstrings explicativos

Total Test Suite (Phase 1 + 2 + 3):
- 53 test methods (18 + 11 + 24)
- 3 test files (test_helper_methods_phase1.py, test_phase2_eskaera_shop.py, test_phase3_confirm_eskaera.py)
- 1,311 líneas de código de tests

Este commit completa la implementación de tests para el refactoring completo de 3 fases,
proporcionando cobertura exhaustiva de todas las funcionalidades críticas del sistema
eskaera (pedidos de grupo cooperativos).

+Test suite for Phase 3 refactoring of confirm_eskaera().
+
+Tests the 3 helper methods created in Phase 3:
+- _validate_confirm_json(): Validates JSON request data
+- _process_cart_items(): Processes cart items into sale.order lines
+- _build_confirmation_message(): Builds localized confirmation messages
+
+Includes tests for:
+- Request validation with various error conditions
+- Cart item processing with product context
+- Multi-language message building (ES, EU, CA, GL, PT, FR, IT)
+- Pickup vs delivery date handling
+- Edge cases and error handling
