feat(signals): register the v1.25 clinical signals through the registry

Add the clinical-signals wave's new measurement types and wire them through
the signal registry so FHIR, correlation eligibility, ingestion, and the
measurement-list surfaces derive from one definition each:

- MeasurementType: PHQ9_SCORE, GAD7_SCORE, GRIP_STRENGTH, PAIN_NRS,
  WAIST_CIRCUMFERENCE, WAIST_TO_HEIGHT (+ AssessmentInstrument enum and the
  MentalHealthAssessment model that backs the screener scores).
- Registry: the six measurement/score signals plus the longevity lab panel as
  kind:"biomarker" entries; the FHIR golden fixture is regenerated in lockstep.
  Grip-strength and waist-to-height carry a null LOINC (NEEDS-VERIFY) and emit a
  local text concept until a stable code is confirmed.
- FHIR: add the survey observation category for the screener / pain signals.
- Labs: extend the biomarker catalogue with ApoB, Lp(a), fasting insulin, and
  the omega-3 index; add LOINC codes for those plus GGT and hs-CRP; add a
  computed HOMA-IR helper.
- Exhaustive maps updated to keep the enum coverage, category, list-meta, and
  personal-record drift guards green.
