Switched container images in `dc-infra.yaml` to a custom Docker registry for better control and consistency across deployments. Added Keycloak with enhanced configurations and updated several container restart policies, memory allocations, and healthcheck settings for improved performance and compatibility.
Replaced Redis with Valkey as the caching backend across infrastructure and application modules. Updated configurations, templates, and health checks to reflect Valkey-specific parameters. Improved compatibility with enhanced configurability, including max memory and memory eviction policy settings.
Updated `dc-infra.yaml` to enable automatic restart (`unless-stopped`), introduce dynamic memory allocations via environment variables, and adjust healthcheck intervals for reduced load. Enhanced `postgresql.conf` with performance tuning comments, schema search path inclusion for Keycloak and app users, and SSL adjustments for internal communication.
- Reorganized `docker-compose.yaml` by splitting it into modular files: `dc-infra.yaml`, `dc-backend.yaml`, `dc-gui.yaml`, and `dc-ops.yaml`.
- Simplified structure by removing redundant `docker-compose.frontend.yaml` and `docker-compose.services.yaml` files.
- Improved maintainability and modularity of service definitions across infrastructure, backend, GUI, and ops layers.
