Removed all remaining Kuzu references from:
- Test fixtures (test_fixtures.py): Changed default database to falkordb, removed kuzu configuration
- Test runner (run_tests.py): Removed kuzu from database choices, checks, and markers
- Integration tests (test_comprehensive_integration.py): Removed kuzu from parameterized tests and environment setup
- Test README: Updated all examples and documentation to reflect falkordb as default
- Docker README: Completely rewrote to remove KuzuDB section, updated with FalkorDB combined image as default
All Kuzu support has been completely removed from the MCP server codebase. FalkorDB (via combined container) is now the default database backend.

The UTC constant was added in Python 3.11. Changed to use
timezone.utc which is available in Python 3.10+.
Fixed ImportError: cannot import name 'UTC' from 'datetime'
This is a major refactoring of the MCP Server to support multiple providers
through a YAML-based configuration system with factory pattern implementation.
## Key Changes
### Architecture Improvements
- Modular configuration system with YAML-based settings
- Factory pattern for LLM, Embedder, and Database providers
