Calibration ignores the units of data and targets #1680

Description

The calibration reads units but never uses them:

• ObservedVariable.unit and CalibrationTarget.unit are read from the UQ file, and
• a reference data column header may carry a unit (name|unit, e.g. level_3_dc_motor.nRPM|rev/min), which is only used to find the column.

The CSV values are compared with the model values as they are. A rev/min column against a model speed in rad/s, or bounds of a target given in another unit than the FMU's, silently give a wrong fit.

Expected

Convert reference data and target bounds/initial values to the units of the model variables (SI + the usual Modelica display units), and stop with an error naming the variable when a unit cannot be converted.
