fix(i18n): drop the "KI"/"AI" prefix from user-facing copy

Marc-Voice rule — the product never names itself "KI" or "AI" in
copy. Settings -> "KI-Auswertungen" becomes "Auswertungen" / "Insights",
the inner "KI-Insights" card heading collapses into the parent section
heading, "Aktiver KI-Provider" becomes "Aktiver Provider", and the
admin "AI Quality" view becomes "Insights Quality".

Sweep across de / en / es / fr / it / pl. Provider product names
(Anthropic, Claude, ChatGPT, OpenAI) are unchanged — those are
proper nouns, not the "AI" label.
