[bug\_fix] Liveness probe failed causing restarts

Run \`kubectl describe pod\` and look for \`Liveness probe failed\`. The kubelet restarted the container because the liveness probe did not respond within \`failureThreshold \* periodSeconds\`. Fix by making the probe check an endpoint that reflects actual health \(not a static file or one that blocks under load\), increasing the \`initialDelaySeconds\` or \`startupProbe\` so slow-starting apps have time, raising \`timeoutSeconds\` for slow endpoints, or tuning \`failureThreshold\`. If the app genuinely deadlocks, fix the deadlock. Do not point liveness at the same path as readiness unless it truly indicates liveness.

Journey Context:
A Java Spring Boot app restarts every few minutes. \`kubectl describe pod\` shows \`Liveness probe failed: Get "http://10.244.1.5:8080/health": context deadline exceeded \(Client.Timeout exceeded while awaiting headers\)\` followed by \`Container ... failed liveness probe, will be restarted\`. The probe path is \`/health\` which performs a deep dependency check and takes 5 seconds under load, but \`timeoutSeconds\` is 1. You change the liveness probe to a lightweight \`/actuator/health/liveness\`, add a \`startupProbe\` with a long failure threshold, and set \`timeoutSeconds: 5\`. Restarts stop.
