chore: release 1.1.0

- 修改.list-table-scroll为overflow-y: scroll，确保显示滚动条轨道
- 修改.list-table-actions为overflow-y: scroll，与数据列保持一致
- 两个表格现在会同时显示滚动条，保持行高完全对齐

+# UI Modernization & Standardization Plan
+
+## Stage 1: Foundation (Global Theme & Layout)
+**Goal**: Establish a consistent visual base and layout structure.
+**Success Criteria**: 
+- Global `ConfigProvider` with a modern theme (v5 tokens).
+- A reusable `MainLayout` component replacing duplicated header/sidebar logic.
+- Unified navigation experience across Admin and User dashboards.
+**Status**: Complete
+
+## Stage 2: Component Standardization
+**Goal**: Replace custom, inconsistent components with Ant Design standards.
+**Success Criteria**:
+- `ListTable` and `DataTable` replaced by `antd.Table`. (Complete)
+- `FormModal` and `ConfirmDialog` replaced by `antd.Modal`. (Complete)
+- `Toast` and custom notifications replaced by `antd.message` and `antd.notification`. (Complete)
+- Custom `Dropdown`, `Breadcrumb`, and `PageLoading` replaced by `antd` equivalents. (Complete)
+**Status**: Complete
+
+## Stage 3: Visual Polish & UX
+**Goal**: Enhance design details and interactive experience.
+**Success Criteria**:
+- Modernized dashboard cards with subtle shadows and transitions. (Complete)
+- Standardized `Empty` states and `Skeleton` loaders. (Complete)
+- Responsive design improvements for various screen sizes. (Complete)
+- Clean up redundant CSS files and components. (In Progress)
+**Status**: In Progress
