Enhance project structure and testing capabilities

- Updated .dockerignore to include additional logs and IDE files, improving Docker build efficiency.
- Added .eslintrc.json for TypeScript linting configuration, ensuring code quality and consistency.
- Refactored Dockerfile to streamline the build process and utilize a slimmer Node.js image.
- Introduced jest-resolver.cjs and jest.setup.js for improved Jest testing configuration and setup.
- Updated jest.config.js to support ESM and added new test patterns for better test organization.
- Enhanced TypeScript schemas to include new device types (media_player, fan, lock, vacuum, scene, script, camera) for comprehensive validation.
- Added unit tests for device schemas and Home Assistant connection, improving test coverage and reliability.
- Updated README.md with new testing instructions and device control examples, enhancing user guidance.
