Implement RBAC Policy Delete Functionality

[KirylSAP]

Description

Add the ability to revoke (delete) RBAC policies with proper confirmation dialog following the existing delete pattern.

Technical Details

Component: DeleteRbacPolicyDialog

File: apps/aurora-portal/src/client/routes/_auth/accounts/$accountId/projects/$projectId/network/-components/SecurityGroups/-components/-modals/DeleteRbacPolicyDialog.tsx

Interface:

interface DeleteRbacPolicyDialogProps {
  policy: RbacPolicy | null
  open: boolean
  onClose: () => void
  onConfirm: (policyId: string) => void
  isLoading: boolean
  error: string | null
}

Design Pattern:

• Follow same pattern as DeleteRuleDialog and DeleteSecurityGroupDialog
• Type "delete" to confirm
• Show policy details in confirmation

Warning Message:

"This action cannot be undone. The target project will lose access to this security group."

Policy Details Box:
Display the policy information:

• Target Project ID: {policy.target_tenant}
• Policy ID: {policy.id}
• Created: {policy.created_at} (optional, if available)

Important Note Message:

"Note: If the target project is currently using this security group (attached to instances or ports), the deletion may fail. Ensure the security group is not in use before revoking access."

Confirmation Input:

Type "delete" to confirm:
[Text Input]

Buttons:

• Cancel: Close without action
• "Revoke Access": Submit (only enabled when "delete" is typed)

Error Handling:

• 409 Conflict: "Cannot revoke access. The target project is currently using this security group. Remove it from their instances first."
• 404: "RBAC policy not found. It may have been already deleted."
• Generic: Display error message from API
