FR-6: Silent Failure

• Polling failures (timeout, network error, relay down) must not trigger the red error screen
• Log the failure to /tmp/aquaping-client.log for debugging
• The user should be unaware of transient failures
• After N consecutive failures (e.g., 3), optionally show a subtle offline indicator (e.g., gray dot in the nav bar) instead of an error screen

FR-7: Chat List Updates

• If a new message arrives for a different chat (not the one currently open), the chat list should also update
• Show an unread indicator on the chat list item (e.g., blue dot, bold text, or subtle highlight)
• The unread state should be persisted in config.json so it survives app restarts
