[Inbound Inbox] Setting to allow .zip file attachments from customers

I want a setting that allows us to enable .zip file attachments for incoming messages. Currently, these are blocked for security reasons, but our customers often need to send evidence (PDFs, images, videos) in bulk. Having a way to whitelist specific extensions or toggle .zip support (similar to Intercom's security settings) would help us avoid forcing customers into extra steps like using external file-sharing services.
