Summary

Issue: for e.g. supramolecular complexes score, the score shown in the overall summary table was the score with weights of 1 applied for all benchmark metrics. this score updates to the correct score once we go onto the category tab and back, but of course we want to see the correct weighted score initially.

decorators.py: build default metric weights before the initial calc_table_scores call, so the saved json starts with the correct weighted score

For my future reference since it took me a second to follow the problem, we just need to set the weights before we calculate the score when we're building the tables during analysis.

The weights are saved either way, but currently the initial score saved to JSON is unweighted, so the weight is only applied when we visit the tab.

Good catch, @joehart2001!
