- Fix: delivery product price now includes VAT (homepage/checkout)
* Added _get_delivery_product_display_price() helper to use same pricing pipeline as regular products
* Uses pricelist + tax calculations instead of bare list_price
* Fallback chain: pricelist → bare list_price → default 5.74
* Updated context in eskaera_shop() and eskaera_checkout()
- Test: test_constraint_cutoff_before_pickup_invalid
* Constraint removed: now allows any combination of cutoff_day and pickup_day
* Updated test to reflect this change (no ValidationError expected)
- Test: test_day_names_not_using_inline_underscore
* Fixed to check sub-template eskaera_order_card_meta where day_names is actually used
* eskaera_page calls this sub-template so day_names context is inherited
