[patch]: add sls_pod_templates support to LicenseService CR for standard and centralized pipelines

[AditIBM931]

Summary

Adds optional sls_pod_templates support to the LicenseService custom resource in both the standard (instance-based) and centralized (standalone) SLS pipelines, allowing operators to configure pod-level settings such as resource requests/limits, replicas, tolerations, and affinity on SLS workloads.

Changes

Standard pipeline (instance-applications/)

• instance-applications/100-ibm-sls/templates/06-ibm-sls_LicenseService.yaml — renders spec.podTemplates when sls_pod_templates is set
• instance-applications/100-ibm-sls/values.yaml — adds sls_pod_templates: {} default
• root-applications/ibm-mas-instance-root/templates/100-ibm-sls-app.yaml — forwards ibm_sls.sls_pod_templates into the ArgoCD application values

Centralized pipeline (sls-applications/)

• sls-applications/100-ibm-sls/templates/06-ibm-sls_LicenseService.yaml — same podTemplates block
• sls-applications/100-ibm-sls/values.yaml — adds sls_pod_templates: {} default
• root-applications/ibm-mas-sls-root/templates/100-ibm-sls-app.yaml — forwards ibm_sls_standalone.sls_pod_templates into the ArgoCD application values
