v1.3.21

• Fix card picker: card now shows a preview thumbnail in the HA card picker (fallback entity weather.home used when no weather entity is found)
• Redesigned settings editor: Forecast Type and Chart Style moved into the Forecast tab; icons consolidated into a single "Icon set" dropdown (HA default / Style 1 / Style 2 / InkyPi); section headers added throughout; text sizes displayed in a 2-column grid instead of a long list
