Converter mappers – domain → DTO translation for converter-related models.

``ConverterInstance`` pairs the registry instance id with the converter's
``ConverterIdentifier`` — the typed, lossless identity projection of the
converter's ``ComponentIdentifier`` — which is the single source of truth on the
wire for the converter's class, supported data types, and constructor params.
