This commit introduces a complete overhaul of the analytics dashboard, replacing the previous simple layout with a modern, data-rich interface.
The new dashboard is built using Tailwind CSS for styling and Chart.js for interactive data visualizations. It provides a more comprehensive and user-friendly view of bot analytics with key metrics, charts for user growth and satisfaction, and a detailed feedback table.
Additionally, this commit fixes a mobile viewport height (`vh`) rendering issue on the chat page to prevent layout shifts on mobile browsers.
