### Additional changelog entries

feat: add Kafka TLS support via Quarkus TLS Registry

fix: add Kafka Streams application-id to prevent consumer group conflict with Reactive Messaging

fix: change default Keycloak realm from quarkus to kvasir   

### Problem
   Previous deployment used **Helm + Helmfile** (marked deprecated). Recent overhaul of configuration
  management in Kvasir called for changes to the Helm chart, making it apparent that maintaining the Helm
  setup is both counterproductive and time-consuming.

   ### Evaluation Process
   After reviewing alternatives including **KubeVela**, **Kustomize**, **YokeCD**, **raw CUE**, and
  **Timoni**, we created a proof-of-concept with raw CUE files. We're now implementing Timoni, as it handles
  multi-environment patterns and service composition that would otherwise require custom integration work.

   ### Solution: Migrate to Timoni
   Use Timoni (CUE-based) for type-safe, declarative Kubernetes deployments:

   - **Reusable service module** - Single generic module for all Kvasir services (monorepo-friendly)
   - **Environment bundles** - Clean override files (dev, staging, prod)
   - **OCI registry support** - Proper versioning and GitOps-ready
   - **Simpler than raw CUE** - Built-in patterns for multi-environment deployments

   ### Progress
   - [x] Evaluate raw CUE approach (complex for multi-repo composition)
   - [x] Create base Timoni module structure
   - [x] Define comprehensive Kvasir configuration schema
   - [x] Wire configuration into ConfigMap generation
   - [x] Test module with monolith deployment
   - [x] Add MVP Kind setup
   - [x] Add Kind test to CI
   - [x] Document deployment workflows
   - [x] Publish module to OCI registry
   - [ ] Remove Helm/Helmfile setup

   ### Benefits vs Helm
   - **Type safety** - CUE validation catches errors early
   - **No templating** - Clean configuration merging with built-in logic instead of Go templates
   - **Better composition** - Share configs across services without copy-paste
   - **Synchronized versioning** - Single version for all microservices (monorepo pattern)
