feat(copilot): simplify project context handling and remove mode parameter

- Remove `selected_project` tuple from MessagesState as it's no longer needed
- Replace tuple-based project selection with direct `project_id` from config
- Remove unused `mode` parameter from llm_call function
- Update topology retrieval to use project_id directly from configurable settings
- Streamline context messages by removing redundant project info formatting
- Move project_id from metadata to configurable section in agent_service config
