Turn Tally AI on or off for the family's bank feeds

Firm-side family relationships only. Select the firm with x-organization-id. Owners, Admins and Staff Admins access all firm families; Staff Members need independent family assignment. Company access does not grant family access. OAuth requires the broad mcp grant, not a narrow banking scope; API keys retain ordinary agent permission scopes. No accounting organizations, portal grants, bank changes, invitations or charges are created. Writes require ordinary firm write entitlement. Cross-firm and inaccessible IDs return 404. Family bank feeds: the firm's bookkeeper posts (clears) each settled row's household category. Personal rows never post journals; posting only records the confirmed category. Requires banking permission. When on, settled rows that match a family rule post automatically; other suggestions wait for the bookkeeper.
