[TASK] Refactor AUV_GUI

[kluge7]

Description of task

1. Refactor Data Management:

• Replace Q-based data storage with Pandas.
• Introduce a DataManager class to handle storage and retrieval of ROS topic data.
• Ensure efficient time-series handling if applicable.

2. Implement Modular Code Structure:

• auv_gui_node.py → ROS node responsible only for subscribing to topics and storing data in DataManager. No UI logic should exist in this file.
• data_manager.py → Manages all stored data using Pandas.
• main_window.py → Manages GUI layout and interaction between widgets.
• widgets.py (or multiple files) → Individual UI components that process and display data.

3. Improve GUI Design:

• Fully utilize MainWindow as the central application frame.
• Widgets should be placed within MainWindow, updating dynamically based on data from DataManager.

4. Code Quality:

• Documentation: Every function should have docstrings (parameters, return types, exceptions).
• Testing: Implement automated tests using pytest to cover core functionality.
• Code Linting & Style: Use black/flake8 for formatting and enforcing good coding practices.

5. ROS Integration:

• Ensure proper topic subscription without direct dependency on UI elements.
• Allow MainWindow to access processed data from DataManager instead of direct topic subscriptions.

6. Improve Maintainability:

• Create a Wiki or documentation portal explaining the new architecture.
• Write developer guides for extending the GUI or adding new widgets.
• Ensure structured logging and error handling for better debugging.

Code Quality

• Every function in header files are documented (inputs/returns/exceptions)
• The project has automated tests that cover MOST of the functions and branches in functions (pytest/gtest)
• The code is documented on the wiki (provide link)
