Fix WC_Settings_Page class loading issue (v1.1.1)

Critical bug fix for settings page initialization:
- Changed hook from woocommerce_loaded to woocommerce_init
- woocommerce_loaded fires before WC_Settings_Page is loaded
- woocommerce_init ensures all WooCommerce core classes are available

This resolves the "Class WC_Settings_Page not found" fatal error
that prevented the plugin from activating successfully.

Version bumped from 1.1.0 to 1.1.1 (patch release).
