APG Withdrawal for WooCommerce

Changelog

0.3.0

• New: digital-content withdrawal waiver checkbox at checkout. Customers buying digital content or virtual services see an optional acknowledgement that requesting the immediate supply waives their right of withdrawal (EU consumer protection requirement). The checkbox is informational; ticking it is not mandatory and does not block order placement.
• The checkbox is injected in both checkouts: classic shortcode (via woocommerce_checkout_before_terms_and_conditions with priority 999) and block-based (via JavaScript that reinserts itself with a MutationObserver to remain right before the native terms checkbox, after any other custom one).
• In the block checkout, a generic cleanup pass removes content injected next to our wrapper by third-party plugins whose selectors over-match (e.g. plugins using .wp-block-woocommerce-checkout-terms-block .wc-block-components-checkbox plus jQuery .after()), avoiding duplicated privacy or marketing notices.
• The customer’s choice is persisted to order meta _apg_withdrawal_digital_waiver ('1' or '0') on both checkouts: the classic checkout reads the POST value on woocommerce_checkout_create_order, the block checkout injects the value into the StoreAPI request body under extensions['apg-withdrawal']['digital_waiver'] and the server hook woocommerce_store_api_checkout_update_order_from_request writes the same meta.
• The block-checkout script reacts to cart changes mid-checkout: it watches StoreAPI cart mutations and, via a nonced AJAX endpoint (apg_withdrawal_check_cart_waiver), re-checks server-side whether the current cart still qualifies, inserting or removing the checkbox without a full page reload.
• New settings section “Digital content waiver” with a single SelectWoo selector for when to show the checkbox: never (default), only on virtual products, on every order, or on products in selected categories or selected products (these two can be combined). Category and product selectors load only when relevant. The “Only on virtual products” mode also matches products with the per-product _apg_withdrawal_type = digital setting, so virtual flag and explicit digital classification are treated as equivalent triggers.

0.2.0

• The frontend form now inherits the native WooCommerce stylesheet (notices, fields, buttons) without requiring custom CSS overrides.
• Notices rendered with wc_print_notice() so they pick up the correct WooCommerce template for both block themes (block-notices/*.php) and classic themes (notices/*.php).
• Dynamic notices (order-not-found feedback and product warning) are pre-rendered server-side via wc_print_notice() and toggled by JavaScript, instead of being built by hand with legacy markup that breaks on block themes.
• Order-not-found feedback follows the native WooCommerce pattern: notice at the top of the form plus woocommerce-invalid class on the email field.
• Buttons use wc_wp_theme_get_element_class_name( 'button' ) for theme and block-theme compatibility.
• Removed inline CSS injected from JavaScript in favour of native WooCommerce notice classes.
• Spanish translation updated to informal “tú” treatment as recommended by the WooCommerce style guide.
