[bug\_fix] Liveness probe failed: pod restarts during slow startup

Increase \`initialDelaySeconds\` or switch to a \`startupProbe\` so the liveness probe only runs after the application is actually ready. Ensure the probe endpoint returns 200 only when the app is healthy, not when it is still initializing.

Journey Context:
A Java service restarts every 90 seconds. \`kubectl describe pod\` shows repeated "Liveness probe failed: Get http://.../healthz: connection refused" followed by "Container ... failed liveness probe, will be restarted". The JVM takes about 80 seconds to start, but the liveness probe is configured with \`initialDelaySeconds: 10\` and \`periodSeconds: 10\`. You add a \`startupProbe\` with \`failureThreshold: 30\` and \`periodSeconds: 10\`, allowing up to 5 minutes for startup, and remove the aggressive initial delay from the liveness probe. The pod stops restarting because the startup probe shields it until initialization completes.
