Add ExportGeneration entity and migration

Introduce the `ExportGeneration` entity for managing export generation data, including related properties such as `exportAlias`, `options`, and `deleteAt`. Add corresponding database migration to create the `chill_main_export_generation` table with necessary constraints and indices. Update `composer.json` to include the `symfony/uid` package.
