"""Add external_meta_deposits for ActualBudget payroll reconciliation.

Daily sync pulls Meta payroll deposits from ActualBudget (the
jhonderson/actual-http-api sidecar) so the dashboard can overlay bank-
deposit reality with `payslip.net_pay`. If the delta exceeds a tolerance
threshold, the payslip parser likely got the net_pay wrong — useful for
catching parser regressions without manual audit.

Idempotent on `actualbudget_tx_id` — rerunning the sync only inserts new
transactions. Deletions in ActualBudget are NOT propagated here (append-
only — the audit trail matters more than a live mirror).
