Meetable RSVP user interface should prompt Code of Conduct agreement(s)

[tantek]

For Meetable events which have one or more Code of Conduct links (per #84), when the user interacts with the RSVP user interface to confirm participation, Meetable should prompt the user with a dialog with one or more links to Codes of Conduct with checkboxes next to each that acknowledges that the user has read and agreed to them.

A minimum viable user interaction here would be just fine, and there is no need to create a whole ticketing and assignment system where different people would RSVP vs agree to the Code of Conduct link(s).

We can learn from the development, use, and iteration of this minimal user interface to then drive future protocol improvements in federated RSVPs via Webmention.
