Release v0.12.4 - weather forecasts, cover control popups, auto-close views and popups

Lots of new features have landed - thanks to @ jwheeler91 for the great suggestions!

Here's what's new:

• Weather forecast card: Add a type: weather-forecast card to any dashboard and see current conditions plus upcoming weather. Choose daily (shows weekday, icon, and high/low range), hourly (shows time, icon, and temperature), or twice-daily. You can pick what shows under the current temperature — high/low, precipitation, or humidity — and limit how many forecast items appear.
• Forecast from a separate sensor: Some weather integrations (like Pirate Weather) don't put forecast data in the entity itself. You can point forecast_entity at a template sensor that does have forecast data, while the main entity still drives current conditions.
• Cover position on long-press: Hold your finger on any cover tile or cover entity row and a position slider appears, alongside dedicated open, stop, and close buttons. Drag to any position, or tap the arrow buttons for full open or close.
• Auto-revert to home screen: Set auto_revert_seconds under the lightdash: section and your dashboard will automatically return to the first view after a period of inactivity — perfect for wall-mounted tablets that should always show the main screen.
• Auto-close popups: Set auto_close_modal_seconds and the dimmer and cover modals will dismiss themselves after a few seconds of inactivity, keeping your display clean.
• Accessibility improvements: Weather condition names and cover control buttons now have proper aria-label attributes for screen readers.
