## Summary
- Wraps `deleteOneWithSource` calls in `.catch()` during workflow/step
destruction so that a missing logic function (valid UUID but already
deleted) no longer crashes the entire destroy operation
- Adds a `Logger` to `WorkflowVersionStepOperationsWorkspaceService` for
the warning
- Fixes test mock to return a resolved Promise and use a valid UUID
## Context
When a CODE step references a `logicFunctionId` that is a valid UUID but
the logic function no longer exists (e.g. deleted by a previous
operation or orphaned), the destroy fails with "Logic function with id X
not found". This blocks users from cleaning up workflows.
## Test plan
- [x] Destroy a workflow with CODE steps whose logic functions already
exist → succeeds as before
- [ ] Destroy a workflow with CODE steps referencing a
deleted/non-existent logic function → succeeds with a warning log
instead of crashing
