📖 Description

This PR implements object count quota enforcement for native and extended Kubernetes resources in the PAC Quota Controller.

What problem does this solve?

• Enables quota enforcement for configmaps, secrets, replicationcontrollers, deployments, statefulsets, daemonsets, jobs, cronjobs, hpas, ingresses, and service subtypes.
• Blocks over-quota resource creation via admission webhooks and updates CRQ status accordingly.

How did you solve it?

• Added object count calculators and admission webhooks for all supported resources.
• Updated controller logic to aggregate and enforce object count quotas.
• Expanded CRQ spec, status, and CRD documentation to list all supported object count resources.
• Updated Helm chart, RBAC, and webhook configuration for new resources.

Key changes:

• New ObjectCountWebhook and ServiceWebhook for admission control.
• Controller logic refactored for object count quota aggregation.
• Helm chart (Chart.yaml, README.md, README.md.gotmpl, values.yaml, CRDs, RBAC, webhook config) updated.
• Unit and e2e tests for object count quota enforcement.
• Service resource calculator and mocks added.
• Pod/storage helpers refactored for extended resource support.

📚 Documentation

• Updated Helm chart documentation (README.md, README.md.gotmpl, values.yaml)
