fix: prevent asset conflicts between React and Grid.js versions

Add coexistence checks to all enqueue methods to prevent loading
both React and Grid.js assets simultaneously.

Changes:
- ReactAdmin.php: Only enqueue React assets when ?react=1
- Init.php: Skip Grid.js when React active on admin pages
- Form.php, Coupon.php, Access.php: Restore classic assets when ?react=0
- Customer.php, Product.php, License.php: Add coexistence checks

Now the toggle between Classic and React versions works correctly.

+ * Higher-order component used to add dispatch props using registered action
+ * creators.
+ *
+ * @param {Function} mapDispatchToProps A function of returning an object of
+ *                                      prop names where value is a
+ *                                      dispatch-bound action creator, or a
+ *                                      function to be called with the
+ *                                      component's props and returning an
+ *                                      action creator.
+ *
+ * @example
+ * ```jsx
+ * function Button( { onClick, children } ) {
+ *     return <button type="button" onClick={ onClick }>{ children }</button>;
+ * }
+ *
+ * import { withDispatch } from '@wordpress/data';
+ * import { store as myCustomStore } from 'my-custom-store';
+ *
+ * const SaleButton = withDispatch( ( dispatch, ownProps ) => {
+ *     const { startSale } = dispatch( myCustomStore );
+ *     const { discountPercent } = ownProps;
+ *
+ *     return {
+ *         onClick() {
+ *             startSale( discountPercent );
+ *         },
+ *     };
+ * } )( Button );
+ *
+ * // Rendered in the application:
+ * //
+ * // <SaleButton discountPercent="20">Start Sale!</SaleButton>
+ * ```
+ *
+ * @example
+ * In the majority of cases, it will be sufficient to use only two first params
+ * passed to `mapDispatchToProps` as illustrated in the previous example.
+ * However, there might be some very advanced use cases where using the
+ * `registry` object might be used as a tool to optimize the performance of
+ * your component. Using `select` function from the registry might be useful
+ * when you need to fetch some dynamic data from the store at the time when the
+ * event is fired, but at the same time, you never use it to render your
+ * component. In such scenario, you can avoid using the `withSelect` higher
+ * order component to compute such prop, which might lead to unnecessary
+ * re-renders of your component caused by its frequent value change.
+ * Keep in mind, that `mapDispatchToProps` must return an object with functions
+ * only.
+ *
+ * ```jsx
+ * function Button( { onClick, children } ) {
+ *     return <button type="button" onClick={ onClick }>{ children }</button>;
+ * }
+ *
+ * import { withDispatch } from '@wordpress/data';
+ * import { store as myCustomStore } from 'my-custom-store';
+ *
+ * const SaleButton = withDispatch( ( dispatch, ownProps, { select } ) => {
+ *    // Stock number changes frequently.
+ *    const { getStockNumber } = select( myCustomStore );
+ *    const { startSale } = dispatch( myCustomStore );
+ *    return {
+ *        onClick() {
+ *            const discountPercent = getStockNumber() > 50 ? 10 : 20;
+ *            startSale( discountPercent );
+ *        },
+ *    };
+ * } )( Button );
+ *
+ * // Rendered in the application:
+ * //
+ * //  <SaleButton>Start Sale!</SaleButton>
+ * ```
+ *
+ * _Note:_ It is important that the `mapDispatchToProps` function always
+ * returns an object with the same keys. For example, it should not contain
+ * conditions under which a different value would be returned.
+ *
+ * @return {ComponentType} Enhanced component with merged dispatcher props.
