fix(gcs): resolve credential conflict and improve backup logging (#7951)

* fix(gcs): resolve credential conflict and improve backup logging

- Workaround GCS SDK's "multiple credential options" error by manually constructing an authenticated HTTP client.
- Include source entry path in filer backup error logs for better visibility on missing volumes/404s.

* fix: address PR review feedback

- Add nil check for EventNotification in getSourceKey
- Avoid reassigning google_application_credentials parameter in gcs_sink.go

* fix(gcs): return errors instead of calling glog.Fatalf in initialize

Adheres to Go best practices and allows for more graceful failure handling by callers.

* read from bind ip
