Enforce proxy vote submission in Salesforce integration

When a proxy vote form is included in the Salesforce integration, it appears after the idea is first created or linked within Salesforce. It is possible to close out of the popup without completing the proxy vote form.

If users skip completing the proxy vote form, valuable context about the idea and the customer's interest in it can be lost.

Make it required to complete the proxy vote form when it is enabled in the integration settings, either via showing it before the linked idea can be submitted or another method.
