A panel can now hold an opaque config blob that the framework stores, moves and deletes
but never reads. It lives on the layout node for the same reason zoom does: the layout is
already persisted per panel and server-side, so a panel's configuration outlives the tab
and is deleted exactly when the panel is.
swapPanels and movePanel now exchange { appType, config } as one unit. They used to carry
only the app type, which would have silently reset a configured panel to defaults on a drag.
Apps read it through usePanelConfig(panelId); PanelSlot already passes panelId to every
registry app, so nothing else in the framework had to change.
