refactor(app-shell): move ObjectView's view tab strip, plugin schema and header chrome into sibling hooks

Move-only split of ObjectViewInner: the view tab items, ViewTabBar and
its own-row face go to objectViewTabBar.tsx; the merged views and the
plugin ObjectViewSchema go to objectViewPluginSchema.ts; the create
button, folded header actions menu and refused-view face go to
objectViewHeaderChrome.tsx. Each hook is called where its block stood.

+refactor(app-shell): the Console `ObjectView`'s view tab strip, plugin schema and header chrome move into sibling hooks
+
+Clause-②: no
+Metadata-protocol: none
+
+Three concerns move verbatim out of `ObjectViewInner` in `views/ObjectView.tsx`. The view tab items, the `ViewTabBar` handed to the list toolbar and its own-row face move into `useObjectViewTabBar` in `objectViewTabBar.tsx`. The views with the open draft merged in and the `ObjectViewSchema` handed to the plugin `ObjectView` move into `useObjectViewPluginSchema` in `objectViewPluginSchema.ts`. The header's create button, its folded actions menu and the list area for a refused view move into `useObjectViewHeaderChrome` in `objectViewHeaderChrome.tsx`. The component passes every input in and reads the returned values. No logic, name or rendered output changes, and the package entry is unchanged.

+What to do: nothing.
