feat(recipes): show the recipe base model in the modal header

Adds a base model pill at the front of the recipe modal's tags row,
showing the full base model name (cards keep the abbreviation since
their overlay width is constrained). Falls back to a dimmed Unknown so
the header layout does not shift when hydration fills the value in.
Hydration now also merges base_model. Translated in all 9 locales.
