Small UI glitch in the transaction processing screen

There is a small UI glitch in the transaction processing screen when displaying the Guardian approved duration.

During a Guardian transaction, the approval duration is displayed at approximately 1.488 sec. The Guardian approved step then changes to the completed/green state, but shortly afterward the displayed duration changes again to approximately 2.033 sec.

Look for the transaction processing screen component, likely in a frontend directory like src/components or src/views. Find where the Guardian approval duration is displayed and updated. Check the state management for timing logic. The fix involves ensuring the duration updates correctly and consistently when the step changes to completed. Test by simulating a Guardian transaction and verifying the displayed duration stabilizes as expected.
