Walkthrough

This pull request removes GitHub Actions workflows for building, pushing, and deploying Docker images alongside Kubernetes configuration files for notification service components in development and production environments.

Changes

Cohort / File(s)	Summary
GitHub Actions Workflows .github/workflows/build-push-image.yaml, .github/workflows/deploy-dev.yaml, .github/workflows/deploy.yaml, .github/workflows/sync-main-to-dev.yaml	Removed reusable Docker build-push workflow and three deployment workflows that handled image building, Kubernetes manifest updates, and rollout orchestration for dev and prod environments. Also removed CI workflow syncing main to dev branch.
Kubernetes Base Deployments deploy/01_server.yaml, deploy/01_worker.yaml	Removed Kubernetes Service and Deployment resources for notification-server and notification-worker, including container configurations, environment variables from ConfigMaps/Secrets, volume mounts for certificates, and health probes.
Kubernetes Dev Environment deploy/dev/01_notification.yaml, deploy/dev/02_ingress.yaml	Removed dev ConfigMap providing runtime configuration (server host/port, VAPID keys, certificate paths) and Ingress resource routing HTTPS traffic to notification-server via Traefik and cert-manager.
Kubernetes Prod Environment deploy/prod/01_notification.yaml, deploy/prod/02_ingress.yaml	Removed prod ConfigMap and Ingress resource mirroring the dev environment configuration for production deployment of the notification service.
