fix(insights): strip metric tokens in recommendation prose + DE component labels

Two related leak fixes traced to the same root: every other AI-prose
surface ran user-visible text through `stripChartTokens()`, but the
recommendation card's always-visible text was rendered directly. The
model embeds `metric:WEIGHT` and friends in the rec text expecting an
inline mini-chart, but the chart slot lives in the EXPANDED rationale
block — so the token had nowhere to be consumed and leaked verbatim
to the DOM.

  - `<RecommendationCard>` now wraps `norm.text` in
    `stripChartTokens()`, matching the contract every other
    rec / finding / summary surface already uses.
  - DE Health-Score component labels surfaced English nouns ("Mood",
    "Medis", "BD") instead of full German. Rename to "Blutdruck",
    "Stimmung", "Einnahmetreue", "Gewicht" so the four sub-bars read
    natively German. The "Mut" the maintainer reported on prod was
    voice-to-text rendering "Mood".
  - i18n-integrity test pins the four component labels so a copy-paste
    regression can't reintroduce the leak.
