Note

Low Risk
Locale-only JSON additions with no application logic changes; verify pl/pt locales if English placeholders are unintended.

Overview
Adds the products.in_stock locale string across 19 language files so the product page stock label ({{lang 'products.in_stock'}} beside the stock count) is translated instead of missing or falling back.

Each file gets one new key under products, immediately after current_stock, with locale-specific copy (e.g. Danish På lager, German Auf Lager, Spanish En existencias). Polish and Portuguese (pl, pt, pt-BR) still use the English phrase "in stock"—worth a quick localization pass if those markets matter.

Untranslated in_stock in locales

Low Severity

This commit adds products.in_stock for several locales, but lang/pl.json, lang/pt-BR.json, and lang/pt.json still use the English value in stock while other updated files have proper translations. The product view renders that key via products.in_stock, so Polish and Portuguese shoppers see English stock text.

• lang/pt-BR.json#L727-L728
• lang/pt.json#L727-L728

@funivan is it expected that translations (in_stock key) for certain languages ​​still have an English version?
