UX: Custom close closure type should default to whatever your close type was changed to on zoom page

[stwalkerster]

Steps:

• Configure preferences to default to using Wikimedia account
• Reserve a request
• Choose the "manual creation" radio button
• Move to custom close the request with a "created"-type template

Expected:

Action to take is set to "Close request as created"

Actual:

Action to take is set to "Create account & close as created"

[!NOTE] This is going to require JS, and JS passing the values through via URL parameters to the custom close form. At the moment, the HTML form that is the zoom page is completely separate to the HTML form that is the custom close page. We can probably move the "skip welcoming" value at the same time.
