Add TestSuiteDetailView for Detailed Test Suite Management

This commit introduces a new StatefulWidget, TestSuiteDetailView, to offer a dedicated view for managing and interacting with individual Test Suites.

Key Features:
- Created a TestSuiteDetailView class that takes a TestSuite object and a TaskViewModel as parameters.
- Added an AppBar with a back button for easy navigation.
- Utilized ListView.builder to display a list of tasks that belong to the selected Test Suite.
- Integrated with existing TaskViewModel to select and delete tasks within the Test Suite.
- Included a Provider for the ChatViewModel to update the current task ID when a task is selected.

This new view enhances the user experience by providing a focused interface for managing tasks within individual Test Suites. This facilitates better organization and navigation for the user.
