refactor(database): remove unique constraint and related files for preview_deployments

- Deleted the SQL file that added a unique constraint on the combination of applicationId and pullRequestId in the preview_deployments table.
- Removed the corresponding entry from the _journal.json to reflect the deletion of the migration.
- Deleted the snapshot file for version 142, which is no longer needed.
- Updated the preview-deployments schema to remove the unique index, reverting to the previous state.
