Clean and organize project structure

Major reorganization:
- Created scripts/ directory for all utility scripts
- Created config/ directory for configuration files
- Moved all test files to tests/ directory
- Updated all script paths to work with new structure
- Updated README.md with new project structure diagram

New structure:
├── src/          # Source code (API + MCP)
├── scripts/      # Utility scripts (start-*.sh, docs_server.py, etc.)
├── tests/        # All test files and debug utilities
├── config/       # Configuration files (JSON, Caddy config)
├── docs/         # Documentation website
└── logs/         # Log files

All scripts updated to use relative paths from project root.
Documentation updated with new folder structure.
