fix: Récupérer l'opération active depuis la table operations

- Corrige l'erreur SQL 'Unknown column fk_operation in users' - L'opération active est récupérée depuis operations.chk_active = 1 - Jointure avec users pour filtrer par entité de l'admin créateur - Query: SELECT o.id FROM operations o INNER JOIN users u ON u.fk_entite = o.fk_entite WHERE u.id = ? AND o.chk_active = 1

+# url\_launcher\_windows
+
+The Windows implementation of [`url_launcher`][1].
+
+## Usage
+
+This package is [endorsed][2], which means you can simply use `url_launcher`
+normally. This package will be automatically included in your app when you do,
+so you do not need to add it to your `pubspec.yaml`.
+
+However, if you `import` this package to use any of its APIs directly, you
+should add it to your `pubspec.yaml` as usual.

+# Platform Implementation Test App
+
+This is a test app for manual testing and automated integration testing
+of this platform implementation. It is not intended to demonstrate actual use of
+this package, since the intent is that plugin clients use the app-facing
+package.
+
+Unless you are making changes to this implementation package, this example is
+very unlikely to be relevant.
