Fix RESULTS_BASE to respect job-specific variable overrides

Move RESULTS_BASE calculation from global variables to runtime
in each job template's script section. This ensures RESULTS_BASE
is calculated using the actual DETECTOR_CONFIG and other variables
after job-specific overrides are applied.

Previously, RESULTS_BASE was evaluated once globally with the
default DETECTOR_CONFIG value and never recalculated when jobs
overrode DETECTOR_CONFIG.
