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.

+write-file-atomic
+-----------------
+
+This is an extension for node's `fs.writeFile` that makes its operation
+atomic and allows you set ownership (uid/gid of the file).
+
+### var writeFileAtomic = require('write-file-atomic')<br>writeFileAtomic(filename, data, [options], [callback])
+
+* filename **String**
+* data **String** | **Buffer**
+* options **Object** | **String**
+  * chown **Object** default, uid & gid of existing file, if any
+    * uid **Number**
+    * gid **Number**
+  * encoding **String** | **Null** default = 'utf8'
+  * fsync **Boolean** default = true
+  * mode **Number** default, from existing file, if any
+  * tmpfileCreated **Function** called when the tmpfile is created
+* callback **Function**
+
+Atomically and asynchronously writes data to a file, replacing the file if it already
+exists.  data can be a string or a buffer.
+
+The file is initially named `filename + "." + murmurhex(__filename, process.pid, ++invocations)`.
+Note that `require('worker_threads').threadId` is used in addition to `process.pid` if running inside of a worker thread.
+If writeFile completes successfully then, if passed the **chown** option it will change
+the ownership of the file. Finally it renames the file back to the filename you specified. If
+it encounters errors at any of these steps it will attempt to unlink the temporary file and then
+pass the error back to the caller.
+If multiple writes are concurrently issued to the same file, the write operations are put into a queue and serialized in the order they were called, using Promises. Writes to different files are still executed in parallel.
+
+If provided, the **chown** option requires both **uid** and **gid** properties or else
+you'll get an error.  If **chown** is not specified it will default to using
+the owner of the previous file.  To prevent chown from being ran you can
+also pass `false`, in which case the file will be created with the current user's credentials.
+
+If **mode** is not specified, it will default to using the permissions from
+an existing file, if any.  Expicitly setting this to `false` remove this default, resulting
+in a file created with the system default permissions.
+
+If options is a String, it's assumed to be the **encoding** option. The **encoding** option is ignored if **data** is a buffer. It defaults to 'utf8'.
+
+If the **fsync** option is **false**, writeFile will skip the final fsync call.
+
+If the **tmpfileCreated** option is specified it will be called with the name of the tmpfile when created.
+
+Example:
+
+```javascript
+writeFileAtomic('message.txt', 'Hello Node', {chown:{uid:100,gid:50}}, function (err) {
+  if (err) throw err;
+  console.log('It\'s saved!');
+});
+```
+
+This function also supports async/await:
+
+```javascript
+(async () => {
+  try {
+    await writeFileAtomic('message.txt', 'Hello Node', {chown:{uid:100,gid:50}});
+    console.log('It\'s saved!');
+  } catch (err) {
+    console.error(err);
+    process.exit(1);
+  }
+})();
+```
+
+### var writeFileAtomicSync = require('write-file-atomic').sync<br>writeFileAtomicSync(filename, data, [options])
+
+The synchronous version of **writeFileAtomic**.

+
+> Easily load and persist config without having to think about where and how
+
+The config is stored in a JSON file located in `$XDG_CONFIG_HOME` or `~/.config`.<br>
+Example: `~/.config/configstore/some-id.json`
+
+*If you need this for Electron, check out [`electron-store`](https://github.com/sindresorhus/electron-store) instead.*<br>
+*And check out [`conf`](https://github.com/sindresorhus/conf) for an updated approach to this concept.*
+
+
+## Install
+
+```
+$ npm install configstore
+```
+
+
+## Usage
+
+```js
+const Configstore = require('configstore');
+const packageJson = require('./package.json');
+
+// Create a Configstore instance
+const config = new Configstore(packageJson.name, {foo: 'bar'});
+
+console.log(config.get('foo'));
+//=> 'bar'
+
+config.set('awesome', true);
+console.log(config.get('awesome'));
+//=> true
+
+// Use dot-notation to access nested properties
+config.set('bar.baz', true);
+console.log(config.get('bar'));
+//=> {baz: true}
+
+config.delete('awesome');
+console.log(config.get('awesome'));
+//=> undefined
+```
+
+
+## API
+
+### Configstore(packageName, defaults?, options?)
+
+Returns a new instance.
+
+#### packageName
+
+Type: `string`
+
+Name of your package.
+
+#### defaults
+
+Type: `object`
+
+Default config.
+
+#### options
+
+Type: `object`
+
+##### globalConfigPath
+
+Type: `boolean`<br>
