Issue #, if available:
Currently, workload application logs collected by fluentbit on Windows doesn't include k8s metadata. The logs looks like

{
    "log": "2025-12-18T20:37:42.4954622Z stdout F Reply from ::1: time<1ms "
}

This change add k8s metadata logs to application logs, similar to application logs on Linux.

{
    "log": "2025-12-19T03:08:02.5138241Z stdout F Reply from ::1: time<1ms ",
    "kubernetes": {
        "pod_name": "windows-server-iis-ltsc2022-1-99b69f97c-2hblx",
        "namespace_name": "default",
