webui: implement comprehensive dark mode support

Add complete dark mode implementation across all web UI components with
theme initialization and consistent styling:

Core infrastructure:
- Update DARK_MODE.md documentation with current implementation details
- Add theme initialization to sketch-app-shell-base component
- Implement ThemeService integration with existing theme toggle system

Component updates with dark mode variants:
- sketch-app-shell: Main container backgrounds and text colors
- sketch-app-shell-base: Top banner, todo panel container with gradient backgrounds
- sketch-chat-input: Input fields, buttons, overlay messages, and drop zones
- sketch-container-status: Info panels, SSH connection displays, and expandable details
- sketch-call-status: Status indicators, banners, and activity states
- sketch-view-mode-select: Tab container, button states, and active tab styling
- sketch-timeline-message: Message bubbles, markdown content, code blocks, and commit info
- sketch-push-button: Overlay popup, form controls, and result containers
- sketch-todo-panel: Todo items, headers, comment modal, and form elements
- sketch-diff-range-picker: Dropdown interface, commit display, and git reference badges

CSS and styling improvements:
- Comprehensive markdown content styling for dark theme
- Code block backgrounds and syntax highlighting adjustments
- Mermaid diagram container styling for dark mode
- Auto-generated link styling with proper contrast
- Git reference badge colors (tags: amber, branches: green, sketch-base: blue)

Interactive element enhancements:
- Consistent hover states across light and dark themes
- Proper focus indicators with accessible contrast ratios
- Loading spinners and progress indicators adapted for dark backgrounds
- Error and success message styling with semantic color preservation

Key implementation details:
- Consistent color mappings: white→gray-900, gray-100→gray-800, gray-200→gray-700
- Preserved brand colors (blue-500, red-600, green-600) that work in both themes
- Maintained semantic color coding for success/error/warning states
- Ensured accessibility with proper contrast ratios throughout
- Theme system integration enables seamless switching without page reload

The web UI now provides a complete, professional dark mode experience
with excellent usability and visual consistency while preserving all
existing functionality and accessibility standards.
