List Transaction Categories
Read-only discovery of the company’s configured transaction categories
and their line item types (nested), with kind and direction so clients
know which fields apply — the ids invoice and reserve writes cite.
Live rows by default; includeDeprecated=true widens both levels to
deprecated rows (marked by deprecatedAt) so old references resolve.
Categories and line item types are configured in the app’s settings —
this surface has no configuration writes.
Required permission: company.payment:read
