test: [orders] 테스트 인프라 정비 및 수주 API 테스트 추가

- TestCase 공통화: setUpAuthenticatedUser(), api(), assertApiSuccess(), assertApiPaginated()
- 기존 10개 테스트 파일의 중복 setUp 코드 → TestCase 상속으로 전환
- Factory 3개 추가: TenantFactory, ClientFactory, OrderFactory
- OrderApiTest 12개 테스트 신규 작성 (목록/생성/조회/수정/삭제/상태변경/인증)
- 발견: 빈 데이터로 수주 생성 가능 (FormRequest 검증 강화 필요)
