fix(ci): stabilize database connection and Python environment

Add PostgreSQL connection retry logic (30 attempts, 2s intervals) to
prevent flaky test failures when PostgreSQL service takes time to start.

Add Python environment variables:
- PYTHONUNBUFFERED: immediate log output (no buffering)
- PYTHONDONTWRITEBYTECODE: skip .pyc generation
- --no-cache-dir: prevent pip cache issues

Fixes intermittent 'connection refused' errors in CI runs.

+
+## 현재 상태
+- ✅ 코드: 모두 커밋됨
+- ✅ 테스트: 214/214 통과
+- ✅ 워크플로우: 준비 완료
+
+---
+
+## 배포 방법 (2단계)
+
+### 📍 1단계: Release 생성 (prepare-release.yml)
+
+**목적:** 코드를 빌드하고 Release 버전을 만드는 단계
+
+**URL 이동:**
+```
+https://gitea.taxbaik.com/kjh2064/QuantEngineByItz/actions
+```
+
+**작업 절차:**
+1. 위 URL에 접속
+2. 왼쪽 목록에서 "Prepare Release" 클릭
+3. 오른쪽 상단 "Run workflow" 버튼 클릭
+4. 팝업에서 파라미터 입력:
+
+   **파라미터: version (버전 이름)**
+   - **의미:** 이 Release의 이름
+   - **입력값:**
+     - **비워두기** (추천): 자동으로 `quant_20260724.0.xxxxx` 형태로 생성
+     - **직접 입력**: `v0.1.20260724` 같이 원하는 이름 입력
+   - **기본값:** (비어있음 = 자동 생성)
+
+5. "Run workflow" 클릭
+6. 실행 완료 대기 (약 5-10분)
+
+**완료 후:**
+- ✅ 빌드 성공
+- ✅ Release 생성됨
+- ✅ Git 태그 생성됨
+- ✅ 아티팩트 업로드됨
+
+---
+
+### 📍 2단계: 배포 실행 (deploy-prod.yml)
+
+**목적:** 생성된 Release를 운영 서버에 배포하는 단계
+
+**URL 이동:**
+```
+https://gitea.taxbaik.com/kjh2064/QuantEngineByItz/actions
+```
+
+**작업 절차:**
+1. 위 URL에 접속
+2. 왼쪽 목록에서 "Deploy to Production" 클릭
+3. 오른쪽 상단 "Run workflow" 버튼 클릭
+4. 팝업에서 파라미터 입력:
+
+   **파라미터: release (배포할 Release 선택)**
+   - **의미:** 1단계에서 만든 Release 중 어떤 것을 배포할지 선택
+   - **입력값:**
+     - **비워두기** (추천): 가장 최신 Release를 자동으로 배포
+     - **직접 입력**: 1단계에서 생성된 버전명
+       - 예: `v0.1.20260724`
+       - 예: `quant_20260724.0.abc1234`
+   - **기본값:** (비어있음 = 최신 Release 배포)
+
+5. "Run workflow" 클릭
+6. 실행 완료 대기 (약 3-5분)
+
+**자동으로 진행되는 작업:**
+1. Release 아티팩트 다운로드
+2. SSH로 서버에 전송
+3. 서버에서 압축 해제
+4. 기존 서비스 중지
+5. 새 버전 배포
+6. 서비스 시작
+7. 자동 헬스 체크 (6가지 항목 검증)
+
+---
+
+## 배포 후 확인
+
+**웹에서 확인:**
+```
+http://178.104.200.7/quantengine/Account/Login
+계정: admin
+암호: quant123!
+```
+
+**SSH로 상태 확인:**
+```bash
+ssh kjh2064@178.104.200.7
+
+# 서비스 상태 확인
+systemctl status quantengine
+
+# 최근 로그 보기 (실시간)
+journalctl -u quantengine -f
+
+# 배포된 버전 확인
+readlink ~/quantengine_active
+```
+
+---
+
+## 문제 발생 시 롤백
+
+**이전 버전으로 되돌리기:**
+
+```bash
+ssh kjh2064@178.104.200.7
+
+# 백업에서 복구
+ln -sfn $(readlink ~/quantengine_active_backup) ~/quantengine_active
+
+# 서비스 재시작
+sudo systemctl restart quantengine
+
+# 확인
+systemctl status quantengine
+```

+
+## 예시 시나리오
+
+### ✅ 시나리오 1: 기본 배포 (추천)
+
+**1단계:**
+- "Prepare Release" 실행
+- version 파라미터: **비워두기** ← 자동 생성
+- 대기
+
+**2단계:**
+- "Deploy to Production" 실행
+- release 파라미터: **비워두기** ← 최신 Release 배포
+- 대기
+
+**결과:** 최신 코드가 운영 서버에 배포됨
+
+### ✅ 시나리오 2: 특정 버전 배포
+
+**1단계:**
+- "Prepare Release" 실행
+- version 파라미터: `v0.1.20260724` 입력
+- 대기 → Release "v0.1.20260724" 생성됨
+
+**2단계:**
+- "Deploy to Production" 실행
+- release 파라미터: `v0.1.20260724` 입력 ← 위에서 생성한 버전
+- 대기
+
+**결과:** 지정된 버전이 운영 서버에 배포됨
+
+---
+
+## 주의사항
+
+⚠️ **반드시 순서대로!**
+- 1단계(Prepare Release) 없이 2단계를 할 수 없음
+- 1단계 완료 후 2단계 실행
+
+⚠️ **파라미터 입력**
+- 오타 없이 정확히 입력
+- 존재하지 않는 버전을 입력하면 오류 발생
+
+⚠️ **배포 중 중단 금지**
+- 실행 중에는 중단하지 말 것
+- 전체 프로세스는 3-5분 소요
+

+
+## 빠른 참조
+
+| 단계 | Workflow | 파라미터 | 권장값 |
+|------|----------|---------|-------|
+| 1 | Prepare Release | version | (비워두기) |
+| 2 | Deploy to Production | release | (비워두기) |
