chore(release): v1.8.7.1 — assessments for every HealthKit metric, one-tap pre-generation

Adds a plain-language assessment to every HealthKit metric page via a
data-driven generator (archetype templates + per-metric metadata, no
per-metric prompt), a one-tap/auto background pre-generation of all
assessments, and the iOS-facing widening of the Insights layout to the
full metric set. Updates the ChatGPT Codex model-slug ladder so
assessments generate again after the backend rotated its identifiers.
Splits the Targets/Sources settings pages, renames the section to
AI Insights, and applies the metric-detail back-nav, dropdown padding,
heading, and Sources-translation polish.
