feat(cert-manager): Add Cloudns issuer and DNS-01 challenge support

- Introduced a new Cloudns issuer configuration for cert-manager. - Created separate tasks for DNS-01 and HTTP-01 challenge issuers. - Updated cert-manager tasks to include Cloudns provider and manage secrets. - Refactored existing LetsEncrypt issuer registration to use new task structure. - Added necessary Kubernetes resources for Cloudns integration, including RBAC and certificates. - Updated Terraform configurations to support new DNS records and service changes. - Adjusted deployment strategies for CoreDNS and Open WebUI applications.
