refactor: Restructure Application layer with vertical slices and AutoMapper

Browse Source 
Vertical slice architecture:

  - Move Features/Documents/{UseCase}/ to {UseCase}/Queries/

  - Query + Handler in SAME file (co-located)

  - Validator in separate file (single responsibility)

New structure:

  - ValidatePdf/Queries/ValidatePdfQuery.cs (Query + Handler)

  - ValidatePdf/Queries/ValidatePdfQueryValidator.cs

  - SwissQrCode/Queries/ExtractSwissQrCodeQuery.cs (Query + Handler)

  - SwissQrCode/Queries/ExtractSwissQrCodeQueryValidator.cs

AutoMapper integration:

  - Add Common/Mapping/MappingProfile.cs

  - Map PdfMetadata -> PdfValidationResult (domain -> DTO)

  - Map SwissQrCodeData -> SwissQrCodeExtractionResult (domain -> DTO)

  - Controllers now thin: pass request to MediatR, AutoMapper handles mapping

DTO improvements:

  - Rename: ValidatePdfResponse -> PdfValidationResult (business-friendly)

  - Rename: ExtractSwissQrCodeResponse -> SwissQrCodeExtractionResult

  - Support BOTH byte[] and Base64Pdf string (XOR validation)

  - Use modern C# 12 collection expressions

Code quality:

  - Use PascalCase for primary constructor parameters

  - Fix LoggingBehavior logging format

Deleted old structure:

  - Features/Documents/ValidatePdf/ (old horizontal structure)

  - Features/Documents/ExtractSwissQrCode/ (old horizontal structure)

  - Common/DTOs/{Request|Response} (replaced with {Result})

Result: Vertical slices, AutoMapper v16.2.0, thin controllers
