Add "custom plan" features in the creation form

[jpaulet]

As Vocdoni, we want to add all the features that the protocol supports but the UI don't support in a "self-service" mode, only in custom project mode.

When clicking one of those options, a popup will appear that will let the user to send a email or schedule a call.

• Customization
• Voting types
• Census types
• Contact us button
• Contact us popup form with schedule option

Visual References and copies:

• Customization
  

• Voting types
  

• Census types
  

Note that we need to increase the separation between the cards in the grid (margin: 15px) and center all the content.
Also, when selecting a census type, we have to hide all the cards and show the census itself, with a "Back" button on top.

• Contact us button (looks like text, but it's a button)
  

• Contact us popup form with schedule option
  

The "Book now" button, is an integration with a external calendar:

`Button code

<script src="https://calendar.google.com/calendar/scheduling-button-script.js" async></script> <script> (function() { var target = document.currentScript; window.addEventListener('load', function() { calendar.schedulingButton.load({ url: 'https://calendar.google.com/calendar/appointments/schedules/AcZssZ29VUbJIqlHtdY32eVUd2OhbjfQLoiHhTAk34Ct6PianaFnwediCb6K021zcX5RaKDdd76eZS-O?gv=true', color: '#3F51B5', label: 'Book an appointment', target, }); }); })(); </script> `

But we can create it with Chakra for having translations and more options.
