> {*}Summary{*}: Job Overview page — make graph container height auto-adjust to viewport and add a recenter affordance.                                                                                                
> *Problem*                                                                                                                                             
>  * The DAG graph area opens at a fixed default height. A horizontal divider lets the user drag it, but until they do, the default doesn't adapt to the viewport — cramped on shorter screens, under-utilized on taller ones.
>  * Users who pan or zoom the DAG have no quick way to restore its centered view. 
> *Changes* 
>  * job-overview.component.ts: default graph height (top) is now clamped to [280, 500] at 40% of the viewport height, and re-applied on window resize. Once the user drags the divider, their choice is preserved (no further auto-adjust).
>  * dagre.component: adds a recenter button (aim icon) in the bottom-right of the graph plus a Ctrl+Space keyboard shortcut; wires up the existing moveToCenter() API.
