[PM-6377] Fix HCaptcha accessibility and resolve Checkmarx warning (#8005)

Turns out the HCaptcha accessibility feature on desktop stopped working a while back. This PR resolves it and tweaks the implementation to use norefeerer and noopener for improved sandboxing. This comes with the slight tweak in behaviour namely we now get the cookie when you click the back button.

To fix hcaptcha not working I needed to use the correct session storage.
