feat(measurements): add ANS_CHARGE and CARDIO_LOAD measurement types

Polar Nightly Recharge and Training Load Pro carry two native signals with
no existing home: the HRV-based autonomic-nervous-system charge (distinct
from the 1-6 recovery band that maps to RECOVERY_SCORE) and the device-native
cardio-load strain figure (distinct from WHOOP DAY_STRAIN and the COMPUTED
STRAIN_SCORE). Add both to the canonical enum (migration 0166) and wire them
through the validation enum, canonical units, plausibility ranges, category
cluster, chart-token allowlist, PR-direction resolver, and the measurement-
list label/icon/colour maps, with labels across all six locales. Both are
device-derived composites, so they read no PR direction and stay out of the
clinical vitals PDF, matching the WHOOP-native score classes.

Regenerate the OpenAPI contract for the two new enum members.
