Fix fatal error and ensure WooCommerce settings tab integration (v1.0.1)

Fixed critical bug preventing plugin activation and improved initialization sequence.

Bug Fix:
- Fixed fatal error: "Class 'WC_Settings_Page' not found" in Settings.php:15
- Root cause: Plugin initialized on 'plugins_loaded' before WooCommerce classes loaded
- Changed initialization hook from 'plugins_loaded' to 'woocommerce_loaded'
- Settings class now extends WC_Settings_Page without errors

Settings Integration:
- Settings page properly integrates as "Composable Products" tab in WooCommerce > Settings
- Tab appears after WooCommerce core tabs (Products, Shipping, etc.)
- All settings fields render correctly:
  - Default Selection Limit (number input)
  - Default Pricing Mode (select dropdown)
  - Display options (checkboxes for images, prices, total)

Technical Details:
- Using woocommerce_loaded hook ensures WC_Settings_Page class is available
- Prevents race condition during plugin initialization
- Settings class registration via woocommerce_get_settings_pages filter works correctly
- No breaking changes to existing functionality

Version bumped to 1.0.1 with updated CHANGELOG.md documenting the fix.

Tested: Plugin now activates without errors and settings tab appears correctly.
