feat: retry future up to three times with a one second delay

[kevmo314]

Add retry logic to the getTwitchBadges method in lib/models/adapters/chat_state.dart to handle the firebase_functions/unavailable error.

• Use a loop to attempt the Firebase function call up to three times.
• Add a one second delay between each retry attempt.
• Catch the firebase_functions/unavailable error and retry if the attempt count is less than three.
• Return an empty list if all attempts fail.

@SputNikPlop can you verify this works? Just check that badges still load.
