feat: add Control Room with containers and stacks management

- Add Control Room page with stacks sidebar and containers list
- Implement container actions (start/stop/restart) with snackbars
- Add container logs viewer dialog
- Add search/filter for both stacks and containers lists
- Add external links for Portainer and Netdata (url_launcher)
- Add VS Code launch configuration for Flutter web debugging

+/// DataGrid component for displaying tabular data.
+///
+/// This library provides a configurable, feature-rich data grid widget
+/// for Flutter applications using Riverpod for state management.
+///
+/// Features:
+/// - Sortable columns
+/// - Row selection (single and bulk)
+/// - Per-row and bulk actions with confirmations
+/// - Search/filtering
+/// - Pagination or infinite scroll
+/// - Custom cell rendering
+/// - Empty, loading, and error states
+/// - Responsive column widths
+///
+/// Example:
+/// ```dart
+/// // Define your data source
+/// final usersSource = InMemoryDataSource<User>(
+///   items: users,
+///   searchMatcher: (user, query) =>
+///     user.name.toLowerCase().contains(query.toLowerCase()),
+/// );
+///
+/// // Define grid configuration
+/// final usersConfig = DataGridConfig<User>(
