Fix HTTP mode authentication and change to root path

- Fix FastMCP HTTP authentication to support environment variables for Fargate deployment
- Change HTTP server path from /mcp/ to / (root) for cleaner URLs
- Allow API keys in environment for containerized deployments
- Add .claude/ and .idea/ to .gitignore to prevent committing sensitive local settings
