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.
