v4.1.0

• Spot-price and tomorrow-price data are now area-scoped: entities and forecast statistics include region/area suffixes (for example fortum:price_forecast_<area>), and the tomorrow-price card renders multiple areas on one card.
• Spot-price fetch now requires explicit priceArea values from Fortum session data (no region fallback behavior).
• Dashboard forecast discovery now uses Recorder statistic id listing and accepts only area-scoped forecast ids.
• Documentation and README were updated for area-scoped behavior, dashboard debugging, and plain Markdown images.
