MinIO設定をCoolify対応に整備し、bucket自動作成を追加

compose:
- MinIOにヘルスチェック(mc ready)を追加し、api/workerはhealthyを待つように変更
- 全認証情報を${VAR:-default}でパラメータ化し、Coolifyの環境変数/シークレットで上書き可能に
- MINIO_SERVER_URL / MINIO_BROWSER_REDIRECT_URL でリバースプロキシ背後の公開URLに対応
- workerの依存先をapiからpostgres+minioに修正し、起動順序のデッドロックを解消

API:
- S3StorageにensureBucket()を追加(HeadBucket→なければCreateBucket、冪等)
- runtime起動時にbucketを自動作成し、minio-init依存を必須ではなくした

.env.exampleにMinIO関連変数を追記
