This PR does not produce any functional changes for our users. It
prepares the branches for workflows by:
- decommissioning `output` and `context` fields or `workflowRun` records
and use newly created `state` field from front-end and back-end
- use `stepStatus` computed by `back-end` in `front-end`
- add utils and types in `twenty-shared/workflow` (not completed, a
follow-up is scheduled
https://github.com/twentyhq/core-team-issues/issues/1211)
- add concurrency to `workflowQueue` message queue to avoid weird branch
execution when using forms in workflow branches
- add a WithLock decorator for better dev experience of
`CacheLockService.withLock` usage
Here is an example of such a workflow running (front branch display is
not yet done that's why it looks ugly) ->
