Refactor: Extract RicTransmissibilityCalculator from completion export

Move transmissibility calculation logic (TransmissibilityData,
connection factor computation, non-Darcy flow calculations) from
RicWellPathExportCompletionDataFeatureImpl into a dedicated
RicTransmissibilityCalculator class. Add unit tests for the
extracted calculator.
