/**
 * Statement-level grouping for the Transaction Categorization listing, forwarded
 * verbatim to the listing API as `transaction_group`. When revenue automation is
 * enabled for the tenant the backend scopes the whole view by the line
 * account_type: `'expense'` -> expense accounts, `'income'` -> income accounts,
 * `'all'` -> both. When off, every value falls back to the legacy expense scope
 * on the backend, so the group is only sent when the gate is on.
 *
 * The wire value for expenses is the singular `'expense'` (matches the backend
 * `TransactionGroup` enum) even though the picker labels it "Expenses".
 * Balance-sheet groups (assets, liability) are reserved for later and are not
 * part of this union yet.
