Create a new Details tab on the Image page that displays the full Dockerfile with base image layers visually highlighted.

Implementation Details:

• Create ImageDetailsTab.tsx component in Containers/Vulnerabilities/WorkloadCves/Image/
• Fetch Dockerfile layers and image components using useRestQuery
• Map components to layer indices to identify which layers are base image layers
• Render all Dockerfile layers using DockerfileLayer component
• Pass {{isBold= {true}

  }} prop for base image layers

• Handle loading/error states
• Show empty state if Dockerfile is unavailable
• Add feature flag gating (ROX_BASE_IMAGE_MANAGEMENT)
• Props: {{ { imageId: string; }

  }}

Acceptance Criteria:

• Tab displays full Dockerfile with all layers
• Base image layers are visually highlighted (bolded)
• Empty state shown when Dockerfile not available
• Loading state displays correctly with centered spinner
• Error handling for failed API requests
• Component is self-contained (manages its own data fetching)
