FAS 1b: Progressive onboarding (3-layer flow)
- Add PROGRESSIVE_ONBOARDING feature flag to KNOWN_FLAGS - Add onboarding_step column to users table (a/b/c) - New backend endpoints: - GET /v1/onboarding/status – check current step + feature flag - POST /v1/onboarding/quick-start – complete Step A (goal + precision) - POST /v1/onboarding/complete-b – complete Step B (diet, allergens, household) - POST /v1/onboarding/complete-c – complete Step C (health profile) - POST /v1/onboarding/skip – GDPR-friendly skip - Refactor mobile onboarding screen into 3 progressive layers - Update auth store with onboardingStep state - Update tab layout to only block on Step A - Update registration to set onboardingStep='a' - Add i18n keys for Step B/C titles across all 12 locales - Add Zod validation schemas (quickStartInputSchema, onboardingStatusSchema) - Add tests for validation and feature flag - Preserve existing /v1/me/onboarding for backward compatibility - Migration: 0004_progressive_onboarding.sql
