fix: route build_per_energy_calibration CTC dict via pht_intier

The rule was passing dsp_par_catalog with tier=intier to
ParsCatalog.get_par_file, producing inconsistent paths like
par/psp/.../par_dsp.yaml (catalog filenames from dsp, directory from psp)
that no rule produces. Select the catalog matching intier so partition
mode reads CTC from par_psp and single-run mode reads from par_dsp.
