* WooCommerce tab only visible when WooCommerce plugin is active.
* Intelligent context detection using backtrace analysis.
* Modern tabbed user interface using WordPress native nav-tab-wrapper.
* Visual status indicators on each tab (green = active with email, red = inactive or no email).
* Legend explaining status indicators for easy understanding.
* Enable/disable toggle for each context (except Default which is always active).
* Fallback chain: Specific context → Default context → Legacy settings.
* Detailed descriptions and examples for each context in the admin UI.
* Reply-To Name field - Now you can specify a name to display with the Reply-To email address (e.g., "Support Team <support@example.com>").
