perf(cdclient): index the columns the lazy lookups search by

Browse Source 
The converted CDClient had no indexes, so each lazy lookup scanned its table (ComponentsRegistry: about
51000 rows, 3.5 ms a query; 0.09 ms with the index). Loading a player with a large inventory spent up to
a minute of the world's main loop in these scans, leaving the client at 35%.
