Upgrade lots of packages (including an upgrade from next 10 to 13) (#57)

- Upgrade all packages (including next) to latest, except:
  - Apollo microservices (there's an issue with how we return
    `apolloServer.createHandler` to the caller as a default export)
  - `graphql` (for compatibility with peer dependencies)
- Also upgrades to the AWS SDK v3 instead of v2 for SES integration.
- Also switches from `react-toast-notifications` (deprecated) to `react-hot-toast`
- Also switches from `react-dnd` (dying) to `@dnd-kit` (it's so much better, I deleted *so* much bespoke code)
- Also switches from `graphql-iso-date` to `graphql-scalars`
