TRANSACTION subtype to OcfEntityType mappings.
These use category='TRANSACTION' with the actual type in the subtype field.
Subtypes use TX_ prefix with UPPER_SNAKE_CASE, SDK uses camelCase.
Exported so that other modules can derive the inverse mapping programmatically
rather than maintaining duplicate data.
