Update Blast

post

https://public-api.luma.com/v1/events/blasts/update

Edit a blast. Only the fields you pass change. Before a blast is sent, everything can change. After it's sent, only subject and content_md can, which updates the post on the event page but not the emails already delivered. Blasts under review can't be edited.
