Funnel default event

Changes

The default event to show ($pageview or $screen) was captured from the event definitions, once they all had loaded. We don't wait for those to load before showing the filters, so that caused problems. This moves the default event name selection into django before the frontend loads.

Checklist

• All querysets/queries filter by Organization, by Team, and by User
• Django backend tests
• Jest frontend tests
• Cypress end-to-end tests
• Migrations are safe to run at scale (e.g. PostHog Cloud) – present proof if not obvious
• New/changed UI is decent on smartphones (viewport width around 360px)

Two broken tests, both seem to be unrelated flakes (ee.clickhouse.views.test.test_clickhouse_action.TestActionPeople and .invitesMembers.js), thus merging.
