fix: notification failing in kubernetes

[cidopenup0]

📌 Description

This PR fixes the notification service failure in the Kubernetes deployment by correcting configuration mismatches and missing secrets.

What does this PR do?

• Fixes a database name mismatch between MySQL and the notification service
• Adds the missing database username to Kubernetes secrets
• Corrects the notification service URL to use internal Kubernetes service discovery

Why is this change needed?

The notification service was unable to connect to its database and receive events due to incorrect database configuration, missing authentication credentials, and improper inter-service communication. These issues prevented notifications from being stored and delivered in the Kubernetes environment.

I need url to be http://api.microforge.manojm.site

[cidopenup0]

alright iam working it

[cidopenup0]

@Manoj-14 i have tried to add ip of ingress-nginx-controller cluster IP but this is considered as bad practice so i consider the old http://notification-service:8083 way as better option and using service names is standard practice for service to service communication

    spec:
+      hostAliases:
+      - ip: "10.102.83.6"  # ingress-nginx-controller ClusterIP
+        hostnames:
+        - "api.microforge.manojm.site"

I worked on it but it not worked for some cases when it is mapped to dns resolver so please update the url

[cidopenup0]

ip is dynamic, so have to update it manually when the k8s namespace gets created

that is why i have been suggesting http://notification-service:8083 thingy
