fix: remove unused db.sqlite related fns

- remove sqlite-db/close! as its not used and didn't make sense to be
  used in other electron ns
- remove sqlite-db/connections atom as its not needed
- remove read-graph as its not necessary
- rename cli.persist-graph as its primary purpose has changed
- update effected scripts
