init-cert-job & backfill-job missing consistent label handling and schema definition for custom labels

[blitz-cmd]

The init-cert-job.yaml & backfill-job template have inconsistent label handling compared to other job templates in the chart, and the values schema doesn't allow custom labels to be defined for this component.

Issues Identified:

1. Inconsistent Label Generation Pattern: The init-cert-job.yaml and backfill-job template doesn't follow the same label generation pattern as other job templates:

• helmless-job.yaml uses: {{- include "cloudzero-agent.generateLabels" (dict "globals" . "component" "helmless" "labels" .Values.components.miscellaneous.helmless.labels) | nindent 2 }}

• config-loader-job.yaml: {{- include "cloudzero-agent.generateLabels" (dict "globals" . "component" "config-loader" "labels" .Values.components.miscellaneous.configLoader.labels) | nindent 6 }}

• backfill-job.yaml only uses: {{- include "cloudzero-agent.insightsController.initBackfillJob.matchLabels" $ | nindent 8 }} and doesn't leverage the generateLabels helper

• init-cert-job.yaml only uses: {{- include "cloudzero-agent.insightsController.initCertJob.matchLabels" . | nindent 8 }} and doesn't leverage the generateLabels helper

2. Missing Schema Definition for Template References for init-cert-job & backfill-job: The template uses {{- include "cloudzero-agent.insightsController.initBackfillJob.matchLabels" $ | nindent 8 }} and {{- include "cloudzero-agent.insightsController.initCertJob.matchLabels" . | nindent 8 }} but there's no corresponding schema definition that would allow users to define these labels in values.yaml.

Team, could these be fix in next version
