Add beta flag for signup pages

As we allow Users to sign up for email alerts we want to explain the
beta status of the signup pages.

International Development Fund Finder.
Add an enabled flag for the email signup link

As we build the email signup feature we want the pages to be visible but
not the link so we can test them.

link in the view.

Add default preselected values to email signup

In order for specific email signups to have different preselected values

Remove email choices for most Finders

With these being live on Preview we realised the desired behaviour isn't
correct. Removing them for now as this is blocking deploys. This commit
also changes the call to be a fetch and returns an empty array if there
are no choices.
