feat: member portal Sprint 1 — dashboard with MemberShell layout and TowerUser profile fields

- Add avatar, hometown, currentLocation, interests, language, digestPreference, directoryVisible fields to TowerUser
- Migration: 20260617200000_add_tower_user_profile_fields
- GET /my/dashboard API endpoint with stats (groups, messages, consents)
- BFF route /api/my/dashboard
- MemberShell 3-column layout (220px nav + flex-1 main + 280px rail)
- Dashboard page: hero card, stat cards, group list, interests chips
- Sidebar returns null for /my paths (MemberShell owns the nav)
