feat(schema): extend MeasurementType with audio-exposure + time-in-daylight (Migration 0052)

Adds three new enum values that close the iOS-17/18 HealthKit coverage
gap before the v1.5 iOS-Swift session locks against Postgres:

  - AUDIO_EXPOSURE_ENV (dBA, environmental noise)
  - AUDIO_EXPOSURE_HEADPHONE (dBA, AirPods listening)
  - TIME_IN_DAYLIGHT (minutes/day, iOS 17+)

Wire-up touches the canonical surfaces:

  - prisma/schema.prisma: MeasurementType + comment block
  - src/lib/validations/measurement.ts: enum + unitMap + VALUE_RANGES
  - src/lib/__tests__/measurement-type-enum-coverage.test.ts: 25 -> 28
    expected types; new entries added to PDF_VITAL_EXCLUSIONS under the
    existing v1.5 clinical-layout gate
  - src/components/measurements/measurement-list-meta.ts: i18n keys,
    Volume2 / Headphones / Sun icons, palette assignments
  - src/lib/insights/chart-tokens.ts: ALLOWED_CHART_TOKENS allow-list
    plus orphan-enum stripper coverage so the LLM cannot leak raw
    upper-snake names into rendered prose
  - messages/{en,de,fr,es,it,pl}.json: typeAudioExposureEnv,
    typeAudioExposureHeadphone, typeTimeInDaylight (en/de translated;
    fr/es/it/pl carry English placeholders matching their existing
    convention for the W5d additions)

The task brief originally listed a fourth value (WORKOUT_ROUTE) as a
sentinel slot. Dropped here because workouts are first-class entities
landing in Migration 0053 with their own table (Workout + WorkoutRoute);
HealthKit also separates HKWorkout from HKQuantitySample. A reserved
sentinel that no real Measurement row will ever take would be a dead
slot for analytics, doctor-PDF allow-lists, and chart registries.
