LiveKit: switch to Recreate deployment strategy. hostPorts (TURN UDP relay
range) block RollingUpdate because the new pod cannot schedule while the
old one still holds the ports.

OpenSearch: set OPENSEARCH_JAVA_OPTS to -Xms192m -Xmx256m. The upstream
default (-Xms512m -Xmx1g) immediately OOMs the container given our 512Mi
memory limit.

login-ui: raise memory limit from 64Mi to 192Mi and add a 64Mi request;
the previous limit was too tight and caused OOMKilled restarts under load.
