Add Security Dashboard page to WebAdmin

[nickna]

Summary

Add a dedicated Security Dashboard page to WebAdmin at /security to expose the existing security monitoring infrastructure through the UI.

Context

The backend infrastructure for security monitoring is complete:

• SecurityMonitoringController in Admin API provides /api/security/events, /api/security/threats, /api/security/compliance
• FetchSecurityService in Admin SDK exposes getEvents(), getThreats(), getComplianceStatus()
• useSecurityApi hook in WebAdmin is ready to use

The only missing piece is the actual UI page.

Requirements

Page Location

• Route: /security or /security-dashboard
• Add to navigation under appropriate section

Dashboard Components

1. Security Overview Card

   • Current threat level indicator
   • Compliance score
   • Active threats count
   • Events in last 24h

2. Security Events Table

   • List recent security events from getSecurityEvents()
   • Filterable by severity (Info, Low, Medium, High, Critical)
   • Filterable by date range
   • Pagination support

3. Active Threats Panel

   • Display threats from getThreats()
   • Show threat type, severity, affected resources
   • Status indicators (active, acknowledged, resolved)

4. Quick Stats

   • Failed auth attempts (24h)
   • Blocked IPs count
   • Rate limit violations

Existing Resources to Use

• useSecurityApi hook at WebAdmin/src/hooks/useSecurityApi.ts
• IP Filtering page patterns at WebAdmin/src/app/ip-filtering/
• Mantine UI components (consistent with rest of WebAdmin)

Acceptance Criteria

• Security Dashboard page accessible at /security
• Navigation link added
• Security events displayed with filtering
• Threat detection results displayed
• Compliance/overview metrics shown
• Responsive design (mobile-friendly)
• Loading and error states handled
• TypeScript strict mode compliant
• ESLint passing

Technical Notes

• Use existing useSecurityApi hook - no new API calls needed
• Follow patterns from other dashboard pages (cost-dashboard, usage-analytics)
• Consider using Mantine's StatsGroup, Table, and Card components
