feat: engagement scoring, birthday auto-emails, stats overview API

- Engagement scoring system (0-100) based on recency, interactions, emails, events, notes
- GET /api/engagement — all client scores with distribution summary
- GET /api/clients/:id/engagement — individual client score with recommendations
- GET /api/stats/overview — system-wide dashboard stats
- Automated birthday check job (pg-boss, daily at 8am UTC)
- Birthday notification emails to advisors (7 days before + day of)
- 73 tests passing (up from 56)
