fix: detect imported recipe language for Translate button (v0.33.1)

URL import extracts content in the source page's own language (no
translation), but never recorded what that language was, so the
Translate button's "recipe.language !== my locale" check always saw
null and showed the button unconditionally. The extractor now returns
a detected ISO 639-1 language code alongside the recipe.

Photo import always writes in the caller's locale already (see its
langInstruction) but never recorded that either — now sets it
directly to locale since it's known, not detected.

+- URL-imported recipes never recorded what language they were actually written in, so the Translate button couldn't tell whether translation was needed — the importer now detects the source page's language, and photo import records the language it always writes in.
