Rename LLM service to Intent service and refactor relevant code

Refactored the `DummyLlmService` to `DummyIntentService` across the codebase for clarity and consistency. Updated variable names, method calls, and documentation to align with this change. This improves code readability and better reflects the service's purpose.
