ConfinementTimeModel.PAZ_SOLDAN_NT was assigned 51, the same value as NCST, making it a silent alias: i_confinement_time=51 dispatched to the NCST scaling and the Paz-Soldan branch in PlasmaConfinementTime.calculate_confinement_time was unreachable. Assign 52, matching the documented switch value in documentation/source/physics-models/plasma_confinement.md, and add enum.unique so a duplicate value can never silently alias again.

Closes #4528
Overview
ConfinementTimeModel.PAZ_SOLDAN_NTshared switch value 51 withNCST, making it a silent Python enum alias:i_confinement_time = 51dispatched to the NCST scaling, the Paz-Soldan branch incalculate_confinement_timewas unreachable, and the documented value 52 was rejected as invalid input.Changes
process/data_structure/physics_variables.py: assign 52 toPAZ_SOLDAN_NT(matching the existing documentation inplasma_confinement.md) and decorateConfinementTimeModelwithenum.uniqueso any future duplicate value fails at import instead of silently aliasing.tests/unit/models/physics/test_confinement_time.py: add a uniqueness test over all switch values and an explicit test that 51 → NCST and 52 → PAZ_SOLDAN_NT are distinct members.Notes for reviewers
N_CONFINEMENT_SCALINGS(=len(ConfinementTimeModel)) goes 52 → 53. I checked the three usages: thehfacarray grows by one element, input validation now accepts 0–52, and the OUT.DAT confinement-comparison table gains one (OCMMNT text) row — no MFILE variables are added, so regression MFILE comparisons should be unaffected.Found during an independent audit of v3.4.2.
