chore: update dependencies and improve chart components

- Updated `foreign-types` to version 0.5.0 and added new dependencies in `Cargo.lock`.
- Removed unused dependencies `chart.js` and `react-chartjs-2` from `package.json` and `package-lock.json`.
- Enhanced `CacheHitRateChart` to use `EChart` for rendering, improving performance and visual fidelity.
- Adjusted styles for `CacheHitRateChart` to ensure proper layout and responsiveness.
- Refactored API query construction in `api.ts` for better readability.
- Updated `HomeMetrics` to support refresh functionality for dynamic data updates.
