… cross-platform compatibility - Updated Dockerfile and hardware.Dockerfile syntax to `docker/dockerfile:1.4` for enhanced features and performance. - Introduced `--link` option in COPY commands to optimize layer caching and reduce image size. - Added a new `entrypoint.sh` script for dynamic configuration and validation of environment variables, improving container startup flexibility. - Included `yq` utility in the base images to facilitate YAML file manipulation within the container, enhancing configuration management capabilities. - Specified `--platform=linux/amd64` for base images to ensure consistent cross-platform builds, addressing potential compatibility issues on multi-architecture setups. - Modified ENTRYPOINT to utilize the new entrypoint script, enabling pre-execution configuration checks and setting a default configuration if none is provided. - The addition of `yq` and changes to the entrypoint mechanism provide a more robust and user-friendly setup process, potentially affecting existing workflows that rely on manual configuration file adjustments. These changes aim to improve maintainability, efficiency, and user experience by leveraging newer Docker features, automating configuration tasks, and ensuring broader compatibility across different computing environments.

- Removed `yq` installation from Dockerfile to reduce image size. - Simplified default configuration file creation in entrypoint.sh by directly writing YAML content, eliminating the need for `yq`. - Removed `yq` installation step from hardware.Dockerfile and adjusted file copying accordingly.
Simplify the entrypoint script by removing the creation of a default configuration file if it doesn't exist. Instead, directly pass the default API listen port configuration to the `go2rtc` command, while still allowing custom configurations through the existing `CONFIG_PATH`. This change ensures that the service can start with default settings without needing to write them to a file, simplifying deployment and configuration management.
