Post an opening balance to a GL account

Posts an opening balance to a GL account via the canonical opening-balance journal entry. Used during entity onboarding and migration to seed account starting balances. Requires accounting:write scope. Idempotent via the Idempotency-Key header. The GL postability guard + balance assertion run on the resulting journal entry.
