List fixed-asset categories
Returns the entity’s fixed-asset categories (Buildings, Machinery,
Vehicles, Computer Equipment, etc.). Each category may carry default
depreciation method + useful-life + MACRS class + GL account routing
that newly-created assets inherit when category_id is supplied.
System-seeded categories are returned with is_system: true and are
non-editable. The endpoint self-heals an empty category list on first
call (idempotent seed of the 8 canonical categories). Requires the
assets:read scope.
