feat(measurements): wire walking-steadiness + audio-exposure-event through every registry

v1.4.30 commit 7 follow-up. The new MeasurementType values land in
every derived registry the canonical enum drives:

  - measurement-list-meta.ts label keys + icons + colors so the
    measurements list view renders both types (Gauge for steadiness,
    Volume2 for the loud-listening event)
  - 6 locale files (de/en/es/fr/it/pl) carry typeWalkingSteadiness +
    typeAudioExposureEvent keys; English-fallback copy for the four
    non-EN/DE locales matches the existing v1.4.25 W8d pattern
  - chart-tokens.ts ALLOWED_CHART_TOKENS list so the LLM can
    reference `metric:WALKING_STEADINESS` + `metric:AUDIO_EXPOSURE_EVENT`
    in prose; dedicated chart components ship alongside the iOS sync
  - the enum-coverage drift-guard test's EXPECTED_TYPES + PDF
    exclusion set so the canonical enum-extension lint stays green

Full unit suite passes (4035 specs).
