Add daily activity digest — Phase B (v0.1.0:77)

Sends a once-a-day internal email to all active admins summarizing each team
member's email activity per investor, plus a team-wide by-investor view
(inbound + outbound, deduped). Narratives are generated on the LOCAL Spark
model, never Claude — the digest is intentionally un-anonymized, so substance
stays on Ten31 infra. This is an internal ops email, exempt from the
'agents draft, humans send' rule (which governs outward LP contact).

- backend/digest_builder.py: per-user + per-investor activity queries
  (soft-delete filtered), per-user Spark narrative with a deterministic
  fallback, two-section plain-text body, and the DB-backed policy resolver.
- backend/email_integration/digest_scheduler.py: always-on daily thread that
  re-reads the policy each cycle and sends once/day; window cursor in
  app_settings so a missed day rolls forward.
- server.py: POST /api/admin/digest/send-now and GET/PATCH
  /api/admin/digest/policy; scheduler wired into main().
- Control lives in Settings -> Admin (enable toggle + send-time dropdown),
  not StartOS actions; env vars only seed the first-boot default.
- Tests: backend/test_digest_builder.py.

+//     member (per-user narrative from the LOCAL Spark model, never Claude) and by
+//     investor (team-wide, inbound + outbound, deduped). Soft-delete filtered.
+//   * backend/email_integration/digest_scheduler.py: an always-on daily thread
+//     that re-reads a DB-backed policy each cycle and sends once/day to all active
+//     admins. Window cursor lives in app_settings (a missed day rolls forward).
+//   * Control moved into the admin panel: app_settings.digest_policy + GET/PATCH
+//     /api/admin/digest/policy + a Settings enable toggle and send-time dropdown
+//     (CRM_DIGEST_ENABLED/SEND_HOUR only seed the first-boot default).
+//   * POST /api/admin/digest/send-now + a "Send Digest Now" button send the real
+//     last-24h digest on demand without touching the daily cursor.
