/**
 * Integration test for the v1.4.18 achievement expansion.
 *
 * Drives a fresh Postgres user through the moments when expansion
 * predicates fire, verifying:
 *   - mood entries persisted as `MoodEntry` rows are picked up by
 *     `getMoodMetrics` (the row shape uses YYYY-MM-DD strings, not
 *     Date objects, which is the most common drift surface)
 *   - measurement counts are split by `MeasurementType` correctly
 *   - earnability flags reflect what the user actually has
 *
 * We don't drive the full HTTP route here because the existing
 * `medication_schedules.days_of_week` migration drift makes the route
 * fail in the integration container; that's a pre-existing issue
 * tracked separately. Instead we round-trip the prisma rows through
 * `buildExpansionMetricValues` and `getEarnabilityFlags`, which is
 * the same code-path the route exercises after the fetch.
