feat: Configure dummy app for development with engine migrations

- Add root route that redirects to missions list
- Fix ApplicationController to fallback to demo user when current_user unavailable
- Configure dummy app to load engine migrations in application.rb
- Create test/dummy/db/migrate directory
- Successfully migrated and seeded database with 26 missions

Now visiting http://localhost:3000 will show the missions selection page!
