  1. Add comprehensive RAG system diagnostic tests and configuration valid… 

    …ation

This commit adds extensive diagnostic tests to identify and resolve "query failed"
issues in the RAG chatbot system, plus improved configuration validation.

New test files:
- test_live_system_diagnostics.py: Tests actual system configuration and vector store status
- test_document_loading_integration.py: Tests document processing with real course files
- test_live_component_integration.py: Tests components (CourseSearchTool, AIGenerator) with real data
- test_actual_api_endpoints.py: Tests actual running FastAPI server endpoints
- test_ai_tool_usage_analysis.py: Analyzes AI tool usage patterns
- tests/README.md: Documents test findings and system behavior

Configuration improvements:
- Add validation in Config.__post_init__() to detect invalid API keys
- Add is_api_key_valid() method for runtime API key validation
- Add helpful error messages for common configuration issues

Key findings from comprehensive testing:
- RAG system is working correctly with proper API key
- All components (document loading, vector store, search tools, AI generation) functional
- AI intelligently chooses between course content and general knowledge
- No "query failed" issues detected in current system
- System exhibits appropriate behavior: course queries use tools, general queries use AI knowledge
