Refactor config to remove env defaults and update docs

Updated the configuration to use null defaults instead of environment variables for 'app_name' and GitHub settings. Adjusted the README to reflect these changes and clarified configuration instructions. Modified the Blade view to fallback to 'app.name' if 'app_name' is not set in the plugin config.
