Upgrade Spring Boot to 3.2.0 to fix RestClient NoClassDefFoundError
- Spring AI 1.0.0-RC1 requires Spring Framework 6.1+ which includes RestClient
- Spring Boot 3.1.1 uses Spring Framework 6.0.x which doesn't have RestClient
- Upgraded to Spring Boot 3.2.0 which includes Spring Framework 6.1.1
- All tests passing, build successful

Add langchain4j dependencies back for server module tool support
- Server module still uses langchain4j's ToolProvider for tool calling
- Added dev.langchain4j:langchain4j to BOM and server dependencies
- Added org.jetbrains:annotations for @NotNull annotations
- AI module successfully migrated to Spring AI
- Server module retains langchain4j for tool functionality

Fix Spring AI migration issues: use getText(), remove OpenAiStreamingChatModel, fix conversationId
- Replace getContent() with getText() for Spring AI message types
- Use OpenAiChatModel for both sync and streaming (Spring AI design)
- Remove conversationId() from MessageWindowChatMemory builder (not in Spring AI API)
- Update all platform implementations (OpenAI, DeepSeek, QianFan, DashScope)
- Fix test files to use correct Spring AI ChatMemoryRepository methods
- All tests now passing
