Add API for resetting chart data and update frontend

Browse Source 
Implemented a new API endpoint `/api/reset-chart-data` in `App.py` to clear chart data history and save state to Redis. Updated the `resetDashboardChart` function in `main.js` to make an AJAX call to this endpoint, providing immediate user feedback. Removed previous logic for handling latest metrics to streamline the reset process.
