[IMP] website_sale_aplicoop: accessibility and responsive polish — phase 8

Quantity control layout: changed from wrapping flex to deliberate two-row
grid so the add-to-cart button sits full-width underneath the stepper,
avoiding accidental line breaks and giving the primary action more pulsing
area. Also removed the /Kg suffix's redundant font rules.

Order card delivery row: reordered to badge-then-date (visually centred),
removed the "Delivery" label, and swapped bg-primary to text-bg-primary for
proper contrast on the home-delivery badge (3.13:1 minimum).

Tooltip translations: moved hardcoded static tooltips from data-bs-title
(untranslatable) to title (QWeb-translatable). Handled the edge case of
"Save Cart" and "Back to Cart" which had translations but no model_terms
reference in the POT, causing the merge to discard them — added the view
reference so translations now apply.

Load-from-history page: added accessibility: a visible status message
("Loading your order…"), a <noscript> fallback with link to the group
order, lang and viewport meta tags, and localised strings for all three
languages. Gave the page a minimal inline style block since it does not
inherit the token system (no website.layout).

Translations: 11 new entries (es/eu/ca) for new/reworded UI strings, plus
two code catalogue entries (products found, Close) that needed the
#. odoo-python comment for _() resolution. Documented the silent-failure
pattern in docs/TRANSLATIONS.md: the POT merge, untranslatable attributes,
and missing code comments.

Tests: 246 passing. Pre-commit: clean.
