The current implementation filters out all node executions whose status is `paused`. Please remove this logic, add unit / integration tests and execute relevant tests.
distinguish between the global timeout and node timeout.
For node-level timeout, the status should be updated to timeout.
for global timeout, the status should be updated to expired.
For status in (timeout, expired, SUBMITTED), the form should not be processed by the `check_and_handle_human_input_timeouts` logic.
only node-level timeout should resume the execution of workflow, global timeout should mark execution as STOPPED.
Update the documentation of HumanInputFormStatus to reflect the facts above.
For users with sandbox plan, the email delivery is not available.
The backend logic should check the plan of the current tenant while sending email. The core check logic should be abstracted in FeatureService. The `HumanInput` node configuration should not validate the presence of `EmailDelivery`.
For enterprise deployment, the email delivery is not limited.
This commit introduces a background task that automatically deletes `WorkflowDraftVariable` records when
their associated workflow apps are deleted.
Additionally, it adds a new cleanup script
`cleanup-orphaned-draft-variables` to remove existing orphaned draft variables from the database.
