- PanelToolbar: allow wrapping and tighten padding on small screens so the
primary action (e.g. "创建 API 密钥") no longer runs off the dialog edge.
- ProviderCard header: let the provider name truncate and pin the model-count
badge and right-side action group with shrink-0 so credits / + controls stay
inside the card on narrow viewports.
- monitoring: stack filters full-width, scrollable tab bar, reduce card/content padding on mobile
- models dialog: provider form modal no longer overflows viewport on small screens; shared panel body padding shrinks on mobile
- plugin logs: reduce horizontal padding on mobile
- Add PanelToolbar/PanelBody primitives so all four settings tabs share
the same top-toolbar + scrollable-body rhythm under the unified header.
- API panel: drop the heavy gray shadowed TabsList; move the create
action into the toolbar next to the tabs, lighten per-tab hints.
- Storage panel: reuse PanelToolbar for the generated-at/refresh bar.
- Account panel: wrap content in PanelBody for consistent padding.
- Models panel: keep the pinned LangBot Models (Space) card at the very
top, above the add-custom-provider row (intentional pin), using
PanelBody instead of a top toolbar.
