[I18N] website_sale_aplicoop, product_origin_char: add Catalan translation

Add ca.po for both addons, matching the existing es/eu coverage
(378 and 4 entries respectively). Add the missing "ca" fallback block
in website_sale_i18n.py alongside the existing es/eu ones, and correct
the i18n README, which falsely claimed complete pt/gl/fr/it coverage
that was never actually present.
