[IMP] website_sale_aplicoop: Phase 3 - Extract helpers from confirm_eskaera()

Phase 3 of cyclomatic complexity reduction refactoring.

Code Quality Improvements:
- confirm_eskaera(): 390 → 222 lines (-168 lines, 43.1% reduction)
- Extracted 3 new helpers reducing main method complexity
- Better separation of concerns: validation, processing, messaging

New Helper Methods:
1. _validate_confirm_json (lines ~550-610): Validates JSON data and order
2. _process_cart_items (lines ~610-680): Processes cart items to sale.order lines
3. _build_confirmation_message (lines ~680-760): Builds multiidioma confirmation message

Phase 1 + 2 + 3 Combined Results:
- Total code refactored: 3 methods (eskaera_shop, add_to_eskaera_cart, confirm_eskaera)
- Total lines saved: 109 + 168 = 277 lines (26% reduction across all 3 methods)
- Total C901 improvements: eskaera_shop (42→33), confirm_eskaera (47→24)
- Created 6 helpers + 2 test files (Phase 1 & 2)

Status: Ready for phase completion
