**Which issue(s) this PR fixes**: **What this PR does / why we need it**: Some requests, such as those made by apps, certain automated scripts, or older browsers, may not include an Origin header. Previously, such requests were blocked by the CORS check, even though they may not necessarily be cross-origin. For CORS, the server is responsible for reporting the allowed origins. The web browser is responsible for enforcing that requests are only sent from allowed domains. So this change updates the CORS handling logic to allow requests with an empty Origin header to pass, ensuring compatibility with legitimate non-browser clients while maintaining security. **Docs Changes**: fluent/fluentd-docs-gitbook#574 **Release Note**: The same as the title.
