feat(auth): validate KYC image URL hosts match MinIO bucket

Closes TEC-2725. Backend KYC presign + submit endpoints already landed in 8f8e20f; this adds the remaining acceptance criterion — host validation on presigned URLs accepted via /auth/kyc/submit. - Add IMediaStorageService.isTrustedUrl(url) — host+bucket check, supports MINIO_TRUSTED_HOSTS for CDN aliases - SubmitKycHandler rejects imageUrls pointing outside our MinIO bucket - Update handler specs with mock + new untrusted-host test Co-Authored-By: Paperclip <noreply@paperclip.ing>

 # GoodGo Platform
 Vietnamese real estate platform — monorepo powered by pnpm workspaces + Turborepo.
 ## Quick Start
 ```bash
 pnpm install
 pnpm db:generate        # Generate Prisma client
 pnpm db:migrate:dev     # Run migrations (needs PostgreSQL 16 + PostGIS)
 pnpm db:seed            # Seed sample data (users, listings, districts)
 pnpm dev                # Start all apps (API :3001, Web :3000)
 ```
 ## Architecture
 - **apps/api** — NestJS backend (CQRS, DDD, clean architecture)
 - **apps/web** — Next.js 15 frontend (App Router, Tailwind, Zustand)
 - **libs/ai-services** — Python FastAPI AI/ML services (AVM, content moderation, NLP)
 - **libs/mcp-servers** — MCP tool server library (property search, analytics, valuation)
 - **prisma/** — Schema, migrations, seed scripts
 - **e2e/** — Playwright E2E tests (API + Web projects)
 ## Key Commands
 | Command | Description |
 |---------|-------------|
 | `pnpm lint` | ESLint (auto-fixable with `--fix`) |

-# Hướng Dẫn Đóng Góp
+# Contributing Guide
-## Kỷ Luật Commit & Push (Bắt Buộc)
+## Error Handling Convention
-> Để tránh conflict khi nhiều agent/engineer làm việc song song, toàn bộ team PHẢI tuân thủ các quy định sau. Nguồn: [GOO-91](/GOO/issues/GOO-91) (chỉ thị từ CEO qua [GOO-88](/GOO/issues/GOO-88)).
+### Overview
-1. **Commit ngay khi hoàn thành task** — mỗi task = một commit (hoặc một chuỗi commit nhỏ liên quan). Không gom nhiều task không liên quan vào một commit lớn.
+All application-layer error handling uses **domain exceptions** from `@modules/shared/domain/domain-exception`. Never import exception classes from `@nestjs/common` in handlers — use the project's own domain exceptions instead.
 2. **Pull/rebase trước khi push** — luôn chạy `git pull --rebase origin <branch>` trước `git push` để giảm merge conflict.
 3. **Push ngay sau commit** — không giữ commit local quá 1 ngày làm việc. Commit không push = rủi ro mất việc + conflict tăng.
 4. **Conventional Commits** — bắt buộc (`feat:`, `fix:`, `chore:`, `refactor:`, `docs:`, `test:`, `style:`, `perf:`). Xem [Quy Ước Commit](#quy-ước-commit) bên dưới.
 5. **KHÔNG push trực tiếp lên `main` / `master`** — luôn dùng feature branch + Pull Request. Branch chính được bảo vệ bằng GitHub branch protection rules.
 6. **PR phải pass CI** (`lint` → `typecheck` → `test` → `build`) trước khi merge. PR đỏ CI không được merge dù đã approve.
 7. **Squash-merge khi merge PR** — giữ history trên `main` sạch, mỗi PR = một commit logic.
 8. **Xóa feature branch sau khi merge** — tránh branch sprawl. GitHub có auto-delete branch sau merge; bật nó trong repo settings.
-### Flow nhanh cho mỗi task
+The `GlobalExceptionFilter` catches all exceptions and normalizes them into a consistent JSON response with structured error codes.
 ```bash
 # 1. Tạo/chuyển sang feature branch (KHÔNG commit trực tiếp vào main)
 git checkout -b feature/goo-xx-short-description
 # 2. Làm việc, khi hoàn thành task:
 git add <files>
 git commit -m "feat(scope): mô tả ngắn"
 # 3. Đồng bộ & push
 git pull --rebase origin main   # hoặc develop
 git push -u origin feature/goo-xx-short-description
 # 4. Mở PR, chờ CI xanh + review, squash-merge, xóa branch
 ```

 ## Quy Ước Xử Lý Lỗi
 ### Tổng Quan
 Toàn bộ xử lý lỗi ở tầng ứng dụng sử dụng **domain exceptions** từ `@modules/shared/domain/domain-exception`. Không bao giờ import các lớp exception từ `@nestjs/common` trong handlers — hãy dùng domain exceptions của dự án.
 `GlobalExceptionFilter` bắt tất cả các exception và chuẩn hóa chúng thành một JSON response nhất quán với error codes có cấu trúc.
 ### Domain Exceptions
-| Exception | HTTP Status | Khi nào dùng |
+| Exception | HTTP Status | When to use |
 |---|---|---|
-| `NotFoundException(entity, id?)` | 404 | Không tìm thấy entity trong database |
+| `NotFoundException(entity, id?)` | 404 | Entity not found in database |
-| `ValidationException(message, details?)` | 400 | Dữ liệu đầu vào không hợp lệ, vi phạm business rule, lỗi tạo value object |
+| `ValidationException(message, details?)` | 400 | Invalid input, business rule violation, value object creation failure |
-| `ConflictException(message)` | 409 | Tài nguyên bị trùng lặp, vi phạm idempotency |
+| `ConflictException(message)` | 409 | Duplicate resource, idempotency violation |
-| `UnauthorizedException(message?)` | 401 | Thông tin xác thực hoặc token không hợp lệ/đã hết hạn |
+| `UnauthorizedException(message?)` | 401 | Invalid/expired credentials or tokens |
-| `ForbiddenException(message?)` | 403 | Đã xác thực nhưng không được phép thực hiện hành động |
+| `ForbiddenException(message?)` | 403 | Authenticated but not authorized for the action |

 ```typescript
 import { NotFoundException, ValidationException } from '@modules/shared/domain/domain-exception';

-Controllers là các tầng ủy quyền mỏng — chúng dispatch tới command/query bus và trả về kết quả. Không cần xử lý lỗi ở tầng controller.
+Controllers are thin delegation layers — they dispatch to the command/query bus and return the result. No error handling needed at the controller level.
 #### Domain Services / Value Objects

-### Kiểu Trả Về Của Repository
+### Repository Return Types
-Tất cả các phương thức đọc của repository phải trả về DTOs được định kiểu rõ ràng — không bao giờ dùng `Promise<any>` hoặc `PaginatedResult<any>`. Định nghĩa read DTOs ở tầng domain cùng với interface của repository.
+All repository read methods must return explicitly typed DTOs — never `Promise<any>` or `PaginatedResult<any>`. Define read DTOs in the domain layer alongside the repository interface.

 # Observability — Read-Model / Projector (RFC-003 Phase 0)
 Grafana dashboards and wiring notes for the read-model observability stack
 introduced in [GOO-192](/GOO/issues/GOO-192) under [GOO-94](/GOO/issues/GOO-94) §6 Phase 0.
 ## Metrics
 All metrics live in the existing NestJS `metrics/` module
 (`apps/api/src/modules/metrics/`) and are scraped via the standard `/metrics`
 endpoint.
 | Metric                                  | Type      | Labels    | Purpose                                                   |
 | --------------------------------------- | --------- | --------- | --------------------------------------------------------- |
 | `read_model_projector_lag_seconds`      | Gauge     | `handler` | Seconds between latest source event and projector cursor. |
 | `read_model_refresh_duration_seconds`   | Histogram | `view`    | Duration of read-model / materialised view refreshes.     |
 | `read_model_reconciliation_drift_total` | Counter   | `model`   | Count of drift discrepancies found during reconciliation. |
 ### Emit points
 Inject `MetricsService` and call:
 ```ts
 metrics.setProjectorLag(handler, lagSeconds);
 metrics.recordReadModelRefresh(view, durationSeconds);
 metrics.recordReconciliationDrift(model, count?);
 ```
 ## Dashboard
 - File: `read-models-dashboard.json` (Grafana schema v38).
 - Import into Grafana (`Dashboards → Import → Upload JSON`), pick the Prometheus
  data source.
 - Variables: `handler`, `view`, `model` — derived from Prometheus label values.
 - Panels:
  1. Projector lag by handler (time series + thresholded)
  2. Max projector lag (stat, RAG 30s / 120s)
  3. Refresh duration p50/p95 by view
  4. Refresh throughput (refreshes/sec) by view
  5. Reconciliation drift rate by model (15m rate)
  6. Total drift events in last 24h (stat, RAG 1 / 10)
 ## Local verification
 ```bash
 pnpm --filter @goodgo/api dev
 curl -s http://localhost:3001/metrics | grep read_model_
 ```
 All three metric families should appear with `# HELP` / `# TYPE` headers even
 before any samples are recorded.

 # Analytics Module
 Vietnamese real estate analytics endpoints: market reports, price trends, heatmaps, district stats, AVM (property valuation), neighborhood scores, POIs, AI-powered listing/project advice.
 ---
 ## Cache Metadata Pattern
 All `/analytics/*` and `/avm/*` responses are **automatically wrapped** by `CacheMetaInterceptor` with a `cacheMeta` field that tells the frontend how fresh the data is.
 ### Response shape
 ```json
 {
  "data": { /* original payload */ },
  "cacheMeta": {
    "cachedAt": "2026-04-21T10:00:00.000Z",
    "nextRefreshAt": "2026-04-21T10:15:00.000Z",
    "source": "cache"
  }
 }
 ```
 | Field | Type | Description |
 |---|---|---|
 | `cachedAt` | `string \| null` | ISO-8601 timestamp when the cache entry was written. `null` for legacy entries or when Redis is unavailable. |
 | `nextRefreshAt` | `string \| null` | ISO-8601 timestamp when the entry will expire. Computed as `cachedAt + ttlSeconds`. `null` when `cachedAt` is null. |
 | `source` | `"cache" \| "fresh"` | `"cache"` = data served from Redis; `"fresh"` = freshly fetched from DB/AI. |
 ### Frontend usage
 Use `cacheMeta` to show a "Cập nhật lúc..." badge or tooltip:
 ```tsx
 const label = cacheMeta.cachedAt
  ? `Cập nhật lúc ${new Date(cacheMeta.cachedAt).toLocaleTimeString('vi-VN')}`
  : 'Dữ liệu mới nhất';
 ```
 ### How it works (for backend devs)
 Three components cooperate:
 1. **`CacheMetaStore`** (`shared/infrastructure/cache-meta.store.ts`)  
   An `AsyncLocalStorage<{ meta: CacheMeta | null }>` that lives for the duration of a single HTTP request. Provides request isolation so concurrent requests never share metadata.
 2. **`CacheService.getOrSet`** (`shared/infrastructure/cache.service.ts`)  
   Cache entries are now stored as JSON envelopes `{ __v: data, cachedAt, ttlSeconds }`.  
   On each call, `getOrSet` writes the resolved metadata into the ALS store:
   - **Cache hit** → reads `cachedAt`/`ttlSeconds` from the stored envelope, computes `nextRefreshAt`, writes `source: "cache"`.
   - **Cache miss / fresh** → writes `cachedAt = now`, computes `nextRefreshAt`, writes `source: "fresh"`.
   - **Redis unavailable** → writes `{ cachedAt: null, nextRefreshAt: null, source: "fresh" }`.
 3. **`CacheMetaInterceptor`** (`analytics/presentation/interceptors/cache-meta.interceptor.ts`)  
   Applied at controller class level via `@UseInterceptors(CacheMetaInterceptor)`.  
   Wraps each response with the ALS-sourced `cacheMeta` after the handler resolves.
 ### Adding the pattern to a new controller
 ```ts
 import { UseInterceptors } from '@nestjs/common';
 import { CacheMetaInterceptor } from '../interceptors/cache-meta.interceptor';
@UseInterceptors(CacheMetaInterceptor)
@Controller('my-endpoint')
 export class MyController { ... }
 ```
 No other changes needed — `CacheService.getOrSet` handles metadata population automatically.
 ### Legacy cache entries
 Entries written by previous versions of `CacheService` (plain JSON, no `__v` envelope) are still served correctly. `cacheMeta` will have `cachedAt: null` and `nextRefreshAt: null` for these entries.
