Smartsheet Citas Auto-Filler

This permission is needed so the extension can detect the open Smartsheet form, display the floating control panel, read the fields already filled in by the user, and trigger the automatic fill/resubmit. Access is limited strictly to the domains app.smartsheet.com/b/form/* and forms.smartsheet.com/*, which are Smartsheet's official form-hosting domains — the extension does not access any other website.
