feat: member portal Sprint 2 — digest history page and restore Digest/DigestConfig schema models

- Restore Digest + DigestConfig models to schema.prisma (wiped by prior git reset)
- Add Tenant.digestConfig / Tenant.digests relations
- GET /my/digest API endpoint (last 20 digests, truncated summary)
- BFF route /api/my/digest
- /my/digest page: digest cards with date, message count, summary preview
- Add Digest nav item to MemberShell sidebar
