feat(auditlog_ng): support destination based configuration

[betinacosta]

Description

The AuditLog NG module currently requires callers to explicitly provide endpoint, deployment_id, and namespace when calling create_client. In SPII-based deployments, these values are stored in a Destination (with tenant-specific fragments) following the ALS SPII v3.0.0 provisioning lifecycle. This change allows create_client to resolve these parameters automatically from a Destination, reducing boilerplate and avoiding misconfiguration.

How to Test

)

print(f"Client created: {client}")
print(f"  endpoint:      {client._config.endpoint}")
print(f"  deployment_id: {client._config.deployment_id}")
print(f"  namespace:     {client._config.namespace}")
