refactor(database): DbMigrator.cs에 KIS 수집 테이블 스키마 초기화 추가

- kis_collection_runs, kis_collection_snapshots, kis_collection_errors 테이블 정의를 DbMigrator.cs의 Migrate()에 추가. - 이를 통해 수집기가 시작되거나 API를 호출하기 전에 스키마가 데이터베이스 초기화 시점에 안전하게 준비되도록 함.
fix: 코드리뷰 즉시수정 4건 + 모니터링 실제 API 연동

+- **핵심 아키텍처 원칙**: Blazor WASM 개발은 **패턴화(Pattern), 템플릿화(Template), 컴포넌트화(Component), MVVM 패턴, API-First 아키텍처**를 최우선 가치로 준수한다.
 - **렌더 모드 표준**: Blazor **Interactive WebAssembly** 를 기본 렌더 모드로 한다. InteractiveServer 는 사용하지 않으며, UI 컴포넌트는 **MudBlazor** 로 통일한다 (Fluent UI 는 폐기).
- **API-First 아키텍처**: Blazor Interactive WebAssembly UI 계층은 비즈니스 로직이나 DB에 직접 결합되지 않고, `IXxxBrowserClient` 등의 추상화된 API 클라이언트(HTTP/RESTful)를 통해서만 백엔드 API와 통신한다.
+- **API-First 아키텍처 (MVVM + FastEndpoints)**:
+  - **백엔드(Server)**: 기존 컨트롤러 구조를 전면 배제하고, REPR(Request-Endpoint-Response) 패턴을 보장하는 **FastEndpoints** 프레임워크를 기반으로 백엔드 API 엔드포인트를 구현하여 단일 책임 원칙(SRP)을 준수한다.
+  - **프론트엔드(Client)**: Blazor WASM 클라이언트는 Razor 컴포넌트(View)와 상태/검증/로직을 갖춘 DTO 및 StateService(ViewModel) 구조의 **MVVM 패턴**을 지향하여 화면 바인딩 정합성을 극대화한다. UI 계층은 비즈니스 로직이나 DB에 직접 결합되지 않고, `IXxxBrowserClient` 또는 추상화된 HttpClient API 클라이언트를 통해서만 백엔드 API와 통신한다.
 - **이중 토큰 인증 패턴**: Access Token(15분) 및 Refresh Token(7일) 이중 토큰 패턴을 적용하며, HttpClient 요청 시 401 Unauthorized를 가로채어 자동으로 localStorage의 Refresh Token으로 토큰을 자동 갱신 및 재시도하는 `TokenRefreshHandler` (DelegatingHandler) 구조를 준수한다.
 - **실시간 알림 (SignalR)**: 실시간 알림 기능은 상태를 직접 동기화하는 용도가 아닌 단순 Event-driven 브로드캐스트 알림으로 설계하며, 클라이언트는 알림 수신 후 API 호출을 통해 최종 데이터를 검증 및 동기화한다.
 - **UI/UX 구현**:
  - MudBlazor 컴포넌트(MudDataGrid Dense + Virtualize)를 사용하여 고밀도(행높이 32px 수준) 및 대량 데이터 성능을 보장한다.
  - CRUD 생성 및 수정 작업 시 화면 플래시를 제거하기 위해 MudDialog 모달 대화상자 패턴을 사용하며, 삭제 작업에는 `ConfirmDialog` 등을 이용해 명시적 사용자 확인을 거친다.
  - 상태 및 등급 구분에는 시각적 가시성을 위한 Status Color Chips(Success, Warning, Error)를 적용한다.
+- **DTO 및 유효성 검증 규칙**: API 입력 모델 및 데이터 전송 객체(DTO) 유효성 검증 시 데이터 어노테이션(DTO Annotation) 방식을 기본적으로 사용하되, 복잡한 비즈니스 조건부 유효성 검증이나 데이터베이스 연동 유효성 검사 등 어노테이션만으로 부족한 영역은 **FluentValidation**을 상호 보완적으로 적용하여 유효성 규칙을 중앙 집중식으로 엄격히 관리한다.
+- **엔지니어링 표준화 지침**:
+  - **표준화 & 컴포넌트화**: UI 요소와 재사용 가능한 비즈니스 코어는 컴포넌트 단위로 구조화하며, 파편화된 개별 커스텀 스타일이나 인라인 데이터 변환을 배제하고 MudBlazor 및 표준 헬퍼 클래스를 공통 활용한다.
+  - **정규화 & 비정규화**: DB 스키마 설계 시에는 정규화 모델을 준수하여 중복과 파편화를 방지하고, 화면 조회 성능이나 BFF 통합 렌더링을 위한 데이터 구조화 단계에서만 안전하게 비정규화된 DTO/뷰 모델을 빌드하여 전송한다.
+  - **데이터 정합성 & 리팩토링**: 모든 비즈니스 도메인의 상태 전이는 ACID 트랜잭션 단위 및 인프라 레이어의 일관성 제어 규칙을 보장하며, 복잡도가 과한 하드코딩 영역은 SRP(단일 책임 원칙) 및 인터페이스 기반 구조로 점진적 리팩토링한다.
+  - **파편화 & 바이브 코드 방지**: provenance(근거) 없는 암묵적 룰이나 감에 의존한 구조(Vibe Code)의 무분별한 탑재를 금지하고, 모든 상태 및 에러 코드는 코드북에 엄격히 등록된 정방형 정규 값만 할당한다.
+  - **하네스 & 테스트 안정성**: 모든 패치는 `Temp/` 및 하네스 테스트 스위트의 빌드 및 통과 로그를 통해 데이터로 증빙한다. 하네스 실패 시 빌드 승격을 전면 차단한다.
+  - **비즈니스 로직 단순화**: 다차원 중첩 조건이나 연쇄 트리거를 제거하고 선형 구조(Waterfall, Sequence)의 단순 프로세스 플로우로 구현하여 추적 가능성을 극대화한다.
 - **코드 및 다국어 규칙**: 모든 관리자 UI 레이블, 폼, 오류 메시지는 한국어로 작성하며, 소스 코드 주석 및 내부 예외 메시지는 영어 작성을 허용한다. 클래스, 메서드, 프로퍼티는 `PascalCase`를 사용하고 비동기 메서드에는 `Async` 접미사를 지정한다.
