Wouter Hermans a3887390c1 feat: add optional dark mode feature (#5065)
* Add optional dark mode feature

This PR adds an optional dark mode to TeslaMate with three appearance options:
- Light (default): Always use light theme
- Follow System: Automatically match OS/browser dark mode preference
- Dark: Always use dark theme

Key features:
- Database-persisted theme preference in GlobalSettings
- Comprehensive dark mode styling for all UI components
- Monochrome map tiles in dark mode (Tesla-inspired aesthetic)
- Instant theme switching without page reload
- No flash of wrong theme on page load
- Defaults to light mode for existing users

Technical implementation:
- New theme_mode field in settings table (migration included)
- CSS custom properties for theme colors
- JavaScript theme detection and system preference monitoring
- LiveView hook for instant theme changes
- Inverted OSM map tiles with grayscale filter for dark mode

Maintains backward compatibility - existing installations will
default to light mode and users can opt-in to dark mode.

* Run treefmt to fix code formatting

* Extract translation strings for theme settings

* Add Dutch, French, and German translations for theme settings

- Dutch: Thema, Weergave, Licht, Donker, Volg systeem
- French: Thème, Apparence, Clair, Sombre, Suivre le système
- German: Design, Darstellung, Hell, Dunkel, Systemeinstellung folgen

* Address review feedback: default to system theme, add tests and documentation
