DLSR-5: use sort_title_tsort instead of sort_title_ssort (#1228)

minor changes:
- fix a bug where we sorted solr field 'exists' ascending (no value first) instead of descending (records with a value come first)
- remove very old solr config - current config is in https://github.com/uclalibrary/calursus-solr
- auto-accept chromatic changes when running after a merge to main
