feat(dashboard): unify icons with Lucide Icons library

- Introduce Lucide Icons via CDN for consistent SVG icons - Replace emoji icons with Lucide SVG icons in sidebar navigation - Fix Sessions/Explorer icon confusion (📁/📂 → history/folder-tree) - Update top bar icons (logo, theme toggle, search, refresh) - Update stats section icons with colored Lucide icons - Add icon animations support (animate-spin for loading states) - Update Explorer view with Lucide folder/file icons - Support dark/light theme icon adaptation Icon mapping: - Explorer: folder-tree (was 📂) - Sessions: history (was 📁) - Overview: bar-chart-3 - Active: play-circle - Archived: archive - Lite Plan: file-edit - Lite Fix: wrench - MCP Servers: plug - Hooks: webhook
