Create the BaseImagesForm component for adding new base image patterns to the system.

Implementation Details:

• Create BaseImagesForm.tsx component in Containers/Vulnerabilities/WorkloadCves/BaseImages/
• Text input for image path/regex pattern
• "Add to base image list" button
• Form validation and submission handling
• Success/error alerts with proper error type mapping (INVALID_IMAGE_NAME, NO_VALID_INTEGRATION, SCAN_FAILED, DUPLICATE_PATTERN)
• Button spinner during mutation
• Disable inputs while submitting
• Props: {{ { addBaseImage: (name: string) => void; baseImagesRequest: UseRestQueryReturn[BaseImage[]]; }

  }}

Acceptance Criteria:

• Form accepts valid image patterns
• Shows appropriate error messages for each error type
• Modal stays open after errors for retry
• Form re-enables after error
• Does NOT make its own API calls (receives callbacks from parent)
