Create E2E tests for the Details tab and layer type filtering functionality.

Test Coverage:

Details Tab Tests:
1. View Details tab:

• Navigate to Image page
• Click "Details" tab
• Verify Dockerfile displays with all layers
• Verify base image layers are highlighted (bolded)
• Verify layer numbers and instructions render correctly
• Verify empty state when Dockerfile unavailable

Layer Type Filter Tests:
2. Apply layer type filter:

• Navigate to Image page → Vulnerabilities tab
• Open compound search filter
• Select "Image component" → "Layer type" → "Base image"
• Verify filter chip appears with correct label
• Verify component table shows only base image components
• Verify CVE counts update based on filtered components

3. Switch filter values:

• Change filter to "Application"
• Verify results update to show application components only
• Remove filter
• Verify all components shown again

Acceptance Criteria:

• Details tab renders correctly with Dockerfile
• Base image layers are visually distinguished
• Filter applies correctly and updates results
• Filter chip displays and can be removed
• Tests work with real backend data
