Fixed settings page appearing twice in WooCommerce settings due to double instantiation of WC_TPP_Settings class.
**Issue:**
- Settings page rendered twice on same page
- WC_TPP_Settings class instantiated twice: once automatically in settings file, once via admin class include
**Fix:**
- Removed conditional wrapper `if (class_exists('WC_TPP_Settings'))` from settings return statement
- Settings class now only instantiated when admin class includes the file via `return new WC_TPP_Settings();`
- Restored v1.1.2 pattern for settings file
**Files Modified:**
- includes/class-wc-tpp-settings.php (simplified return statement)
