- as updates to API Sessions can now happen later than the last time
they were active, updatedAt is no longer the correct representation of
the last activity an API Session had
- move all logic that used updatedAt to lastActivityAt
- add migration to set lastActivityAt
- remove old JSON schema, unsused code
- remove unused variables from base router functions
- rework all API entities
- rework all links
- fix lint issues
- adds error conversion logic
- update tests as needed
- fix up go test
- fix backwards compat w/ non json enroller
