[TASK] Implement Record Button to Capture Data Stream for Debugging

[niclassvardal-boop]

Description of task

Add a “Record” button to the GUI that allows operators to capture the full telemetry/data stream during operation. The recorded data should be saved locally for later debugging, replay, or analysis.

Components:

• Record button: UI element to start/stop recording; toggle state with visual feedback
• Data capture logic: backend handler to stream and save incoming data (e.g. ROS messages, Foxglove topics)
• File management: Save the data to timestamped file or user-defined location
• Status indicator: Show recording status (e.g. "recording..." or blinking red dot)

Suggested Workflow

Add QPushButton with toggle behavior and recording icon

• Connect button to backend recording logic (e.g. ROS bag, Foxglove WebSocket stream)
• Implement file saving with timestamped filenames
• Add visual indicator for active recording
• Ensure recording stops gracefully on GUI exit or error
• Log recording events to GUI log panel
