Save flow as draft
### Feature description

As a Kestra beginner,

I imagined I could start a flow and leave it as a draft,

But I couldn’t save something with syntax errors

As a result, I spent more time than expected fixing my flow,

So I end up being late for other activities in my day.

*What would have helped?*

→ A way to save in draft. *Maybe in a deactivated mode?*
