Pull request overview

This PR improves runtime diagnostics around network startup failures: (1) adding clearer SSL runtime failure logging for REST-based LED devices and (2) enhancing port-binding error reporting (notably for Windows scenarios where the Web UI fails to start when a system proxy is enabled).

Changes:

• ProviderRestApi: validate CA certificate parsing, preserve existing CA list, and log explicit errors when Qt SSL is compiled in but runtime SSL libraries fail to load (plus a message for QT_NO_SSL builds).
• NetUtils::portAvailable: log socket binding failure details (error code + string) and add special handling for SocketAccessError.
• Update CHANGELOG.md with entries for the Windows/UI error-detail improvement and the ProviderRestAPI SSL error logging.
