-- Dimensions PR7 (producers): source documents carry dimension tags so the
-- entry generators can propagate them onto journal lines.
--
--   invoices.default_dimensions / supplier_invoices.default_dimensions
--     {sie_dim_no: code} bag applied to EVERY generated line (issuance,
--     payment, credit — payment vouchers re-propagate from the linked
--     invoice under both accounting methods).
--   invoice_items.dimensions / supplier_invoice_items.dimensions
--     per-item bag merged OVER the invoice default on the revenue/expense
--     line that item books to (item wins per key).
--
-- Same shape + CHECK as journal_entry_lines.dimensions (20260702084500).
-- No indexes: these columns are read via their parent row when generating
-- entries, never containment-queried — reporting queries hit the GIN on
-- journal_entry_lines. NOT NULL DEFAULT '{}' is metadata-only on PG11+.
--
-- pg-test: covered-by — plain column adds with a type CHECK, no
-- trigger/RPC/RLS/DEFERRABLE change. Propagation logic is TS-side
-- (lib/bookkeeping/{invoice,supplier-invoice}-entries.ts unit tests).
