The rails default CSRF protection was disabled in #1317
The POST routes in this application are postcode lookups to an external API. So we don't currently need CSRF protection, but this is being flagged by the scanner as a vulnerability. Let's turn it back on across the application, and just disable it on four specific routes. This means if the application changes in the future we aren't caught out (assuming we're covered by default CSRF protection).
