[parneetbrar234-svg]

Description

Added a new Security Analytics Dashboard to provide visual insights into vulnerability trends, scan statistics, and target risk analysis.

Features Added

• Analytics page (/analytics)
• Vulnerability trends line chart
• Severity distribution pie chart
• Most vulnerable targets bar chart
• Scan success vs failure analytics
• Summary metric cards
• Time range filters (7d / 30d / 90d)
• Analytics navigation item
• Responsive dashboard layout

Notes

Currently the dashboard uses mock analytics data and is structured for future backend integration and real-time updates.

@utksh1 plz review my PR.

Thanks for the dashboard work. I can't merge this as-is because the production Analytics route is wired into navigation with hard-coded sample metrics (, , , and ). That would show fictional security data to users. Please connect the page to real backend/API data, or keep it behind an explicit demo/storybook-only surface. Also restore the AppShell formatting so the navigation arrays and mobile nav remain consistent.

Clarifying the requested change: the production Analytics route currently uses hard-coded sample arrays: vulnerabilityTrend, severityData, targetRisk, and scanStats. Please replace those with real API/backend data, or keep the mock dashboard out of production navigation.

@utksh1 Removed the Analytics dashboard from production navigation and routing because it currently relies on mock data. The dashboard remains in the codebase and can be reintroduced once real backend/API analytics data is implemented. Also restored AppShell mobile navigation consistency.

Re-reviewed after the latest update. This still cannot merge while the production Analytics route/nav show hard-coded sample security metrics instead of real API/backend data. Please replace the mock arrays with real data or keep the dashboard out of production navigation.
