Implement system theme support and dark mode infrastructure

Add comprehensive theme management system with iOS system integration: - System theme detection: App follows iOS dark/light mode preferences via ThemeMode.system - Theme provider: Centralized theme state management with Riverpod (defaults to dark mode) - Settings toggle: Segmented button UI for Light/Dark/Auto theme selection - iOS system UI: Status bar and navigation bar adapt to current theme brightness Dark mode map styling (Android-ready): - DarkModeMapComponent: Reactive theme change detection with didChangeDependencies - Map style application: Custom dark JSON style for navigation maps - Theme-aware styling: Automatically applies/resets map style on theme changes - Note: Map styling currently Android-only due to iOS SDK limitations Updates: - main.dart: System UI overlay styling for iOS, theme provider integration - settings_page.dart: SegmentedButton theme toggle with icons - providers.dart: themeModeProvider for app-wide theme state - dark_mode_map.dart: Theme reactivity and style application logic - navigation_page.dart: Theme detection infrastructure (prepared for future use) Design philosophy: - Follow system preferences by default for native iOS experience - Manual override available for user preference - Clean separation between Flutter UI theming and native map styling 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
