Repurpose Communications tab as admin-only email-activity panel (v0.1.0:80)

The Communications tab is now an admin-only search over captured Gmail
(email_* tables), part of consolidating on the fundraising grid + email
capture as the canonical system of record.

- New GET /api/email/activity (admin-enforced server-side): filter by
  investor / mailbox / direction with free-text search over subject,
  snippet, and sender. Query logic in db.query_email_activity.
  - Soft-delete honored on the per-mailbox sighting (emails carry no
    deleted_at; deletion lives on email_account_messages).
  - Direction decided at the email level (outbound if the sender is one of
    our mailboxes), mirroring digest_builder.
  - Graveyard investors are hidden from the filter dropdown (CRM-wide
    graveyard=0 convention) but their email stays visible in the list and
    findable by free-text search — this is an audit surface.
- Communications page rewritten to render the panel; the classic manual
  "Log Communication" form is retired (the grid context menu remains the
  manual-log path). Nav item + page are admin-only.
- Tests: email_integration/test_email_activity_panel.py (filters,
  per-sighting soft-delete, roll-ups, graveyard handling, route 401/403);
  full suite 22/22. Frontend render verified via a jsdom mount smoke test
  plus the pinned classic-runtime Babel transform.

Code-only, no schema migration (version migrations are no-ops).
