fix(modals): use Modal.useModal hook for proper dark mode theming

Modal.confirm() bypasses the theme provider context by rendering directly
to document.body. This change uses the useModal hook which renders modals
within the component tree, ensuring they inherit theme context properly.

Changes:
- Replace Modal.confirm() with modal.confirm() from useModal hook
- Add contextHolder to JSX to provide rendering container
- Applied to ThemeList and EmbeddedModal components

This fixes dark mode theming issues where confirmation modals would
appear with default Ant Design styling instead of themed styling.
