TabularDataColumnMetadata
Per-column metadata. display_type reuses the canonical field DisplayType
(TEXT, NUMBER, CURRENCY, PERCENTAGE, DATE, ...) so the client renders columns
the same way it renders entity fields. Currency rendering uses the account's
own currency setting — no per-column override.
