Subject: [PATCH] Refactor dashboard and components, remove echarts

Replaces echarts-based usage pie chart with a custom SVG implementation, removing the echarts dependency. Improves caching for version and system info requests, simplifies page background to static elements, and switches dashboard state to use localStorage for persistence. Also removes polling from hitokoto and updates button styling in system info.
