fix: eliminate untyped repository returns and standardize DomainException usage across all handlers
...
- Create typed DTOs (ListingDetailData, ListingSearchItem, ListingSellerItem) for repository read methods
- Replace all Promise<any> and PaginatedResult<any> with concrete types in repository interface and implementation
- Remove `as any` casts in search params by using Prisma enum types (TransactionType, PropertyType)
- Migrate all 16 handlers from NestJS built-in exceptions to domain exceptions (NotFoundException, ValidationException, etc.)
- Add CONTRIBUTING.md documenting error handling convention
- All 230 tests pass, typecheck clean

fix(payments): harden payment flow with idempotency keys, amount validation, and magic byte file validation
...
- Add dedicated idempotencyKey column with unique constraint (userId, provider, idempotencyKey) to prevent duplicate payments at DB level
- Add @Min(1) @Max(100B) validators on amountVND in CreatePaymentDto to reject invalid amounts at API boundary
- Replace read-check-write callback handler with atomic updateIfStatus to eliminate race condition on concurrent callbacks
- Add magic byte verification in FileValidationPipe to validate file content matches declared MIME type server-side
