Replace Notion custom CMS with GraphCMS

[replygirl]

Low priority. Right now we load landing page content from Notion, would be better to have it tightly structured in GraphCMS on their free plan.

• Migrating status record:
  • Move live status to Event model
  • Infer actions in the app, based on the latest Event data
  • Move streamConfig (discordInviteUrl, chatConfig, videoConfig) into repo as defaults and add fields to Event for optional override
• Migrating events database:
  • Create Event model
    • Add dedicated notes field
    • Add dedicated Archive field
• Migrating docs database:
  • Reupload imgur files under GraphCMS
  • Move files in /public out of repo into GraphCMS

Make sure to figure out the dev workflow—will we be configuring in the UI and promoting an environment manually, or will we be managing schema in code and updating the main environment on build?
