✨ New Features & ⬆️ Improvements & 🐛 Bug fixes

🔤 Font size options

• font_size — scales the whole card (e.g. 1em, 1.5em, 18px).
• keypad_font_size — scales just the keypad digit buttons (e.g. 1em, 5em).

Thanks to @asherflynt for the font-size contribution (#8).

🎨 Brand-new configuration editor

The card's visual editor has been rebuilt from scratch:

• Tabbed layout — options split into 8 sections (Main, Keypad, Zones, Display, Colors, Labels, History, Automations), shown as a 2-row tab bar instead of one long list.
• Grouped cards — each section is organized into clear, icon-led cards with short descriptions, so settings are easier to find.
• Sliders for keypad width and height, plus a number stepper for the history "max items".
• Cleaner toggles and color swatches, dashed "add" buttons, and per-item remove buttons.
• The "add automation" action now reads Add Automation / Input Boolean to make clear both entity types are supported.

Your existing YAML is fully compatible — every option reads and writes exactly as before. No config changes required.
