Auto-create databases in migrations, remove setup.sql dependency

- feed-requests: Add ensureDatabase: true to MikroORM config
- user-feeds-next: Add ensureDatabaseExists() to create DB before migrations
- Remove setup.sql volume mount from docker-compose.base.yml

This allows the released compose file to work standalone without
requiring local SQL files.
