feat: Add complete HSP implementation with integration tests passing

Initial implementation of HTTP Sender Plugin following TDD methodology with hexagonal architecture. All 313 tests passing (0 failures). This commit adds: - Complete domain model and port interfaces - All adapter implementations (HTTP, gRPC, file logging, config) - Application services (data collection, transmission, backpressure) - Comprehensive test suite with 18 integration tests Test fixes applied during implementation: - Fix base64 encoding validation in DataCollectionServiceIntegrationTest - Fix exception type handling in IConfigurationPortTest - Fix CompletionException unwrapping in IHttpPollingPortTest - Fix sequential batching in DataTransmissionServiceIntegrationTest - Add test adapter failure simulation for reconnection tests - Use adapter counters for gRPC verification Files added: - pom.xml with all dependencies (JUnit 5, Mockito, WireMock, gRPC, Jackson) - src/main/java: Domain model, ports, adapters, application services - src/test/java: Unit tests, integration tests, test utilities
