**What**
- Add authentication endpoints:
- `/auth/[scope]/[provider]`
- `/auth/[scope]/[provider]/callback`
- update authenticate-middleware handler
- Add scope field to user
- Add unique constraint on scope and entity_id
note: there's still some remaining work related to jwt auth to be handled, this is mainly focussed on session auth with endpoints
