🔧 Improvements

✨ New Features

• Tabbed editor layout — Global Settings and each Entity now organized under tabs (General, Colors, Icons, Labels) instead of nested collapsibles. Faster navigation, less scrolling.
• Duplicate entity — New copy button in entity header row. Clones all settings and auto-expands the new entry.
• Tooltips — Hover info icons next to key fields explain what each option does.
• Entity friendly name in header — When custom name is empty, entity header shows the switch entity's friendly name instead of "Entity #1".

🛠 Fixes

• HA 2026.4 compatibility — Input background colors fixed. New --ha-color-form-background and related CSS custom properties applied globally for Web Awesome migration.
• Dropdown selection fixed — Replaced broken ha-select with ha-selector (select type). Button Position dropdown now works reliably.
• "Use global" option fixed — Sentinel value approach resolves empty-string selection issue in ha-selector.

🎨 UI Improvements

• Panel headers with colored icons and subtitles
• Entity count badge on Entities panel
• Tab bar with border and active state highlight
• Responsive grid layout for mobile
• Smooth transitions and hover effects
• Reset buttons on override tabs (Colors, Icons, Labels)
• Removed redundant "Default: ..." hints and entity chip badges for cleaner look
