refactor(db/schema): align TypeScript schema with production

Path A baseline reconciliation. drizzle-kit pull against tia_prod showed
prod had drifted well past schema.ts because legacy hand-rolled migrations
0003-0015 wrote to the DB but were never reflected back into TypeScript.

Shared-table drift fixed:
- users:          + password_hash, + password_updated_at
- families:       + tier, + max_children, + max_members
- children:       col is 'stage' (kept JS key currentStage -> stage);
                  'image_url' not 'profile_photo_url'; birth_date is DATE;
                  sex nullable; dropped phantom stage_overrides
- family_members: dropped phantom display_name
- family_invites: dropped phantom display_name, accepted_at
- audit_log:      + resource_id, + resource_type; metadata -> jsonb; +5 indexes
- memories:       + vision_tags (text[]), + vision_embedding (vector 1536)
- logs.ts:        'diapers' phantom table renamed to diapersLogs ('diapers_logs')

19 missing tables added across new files:
- admin.ts:     admins, admin_sessions, password_resets
- support.ts:   support_tickets, support_responses
- ai.ts:        chat_sessions, chat_messages, ai_usage
- medical.ts:   medicines, medication_doses, allergies, illness_logs, doctor_visits
- affiliate.ts: member_profiles, recommended_products, product_clicks
- logs.ts:      + milestone_achievements
- audit.ts:     + log_corrections

BUG FIX: schema/index.ts never re-exported ./logs — Drizzle was blind to
feeds/sleeps/vaccinations/growth/medications. Now exported.

Verified: tsc --noEmit has zero non-test errors. Dropped phantom columns
confirmed to have zero references in src/.
