Display Watchdog Status in App

[amalnanavati]

As of ada_feeding#50, there is a topic (the watchdog topic) that publishes the results of a variety of safety checks (with the DisgnosticArray msg type). If any check does not succeed, the robot is unable to move.

It is important for users to be able to see the results of the watchdog tests, so they can understand what is wrong and potentially fix it. This issue is focused on rendering the watchdog status to the user.

I think the best way to do this would be the following:

• Rename the "Video" Modal to something like "Robot Info"
• In that modal, display each test status, one per line. The line should show an icon/emoji (e.g., ✅ or ❌) for whether the test passed, then name field of the DiagnosticStatus message, and an optional button/arrow to show more details. If the user decides to show more details, it should show the entire message field of the DiagnosticStatus message.
