Minimal repro: Adobe Acrobat extension + Chrome 151+

Submitting this form does a POST to /relatorio, which returns a PDF inline (no Content-Disposition: attachment), the same way our production report actions do.

With the Adobe Acrobat extension enabled on Chrome 151.0.7922.72+, printing from the extension's viewer triggers a secondary GET request to this same URL, which returns 404 because this route only accepts POST.
