feat: Add OTP resend timer functionality to ConfirmCode - [CU-869bgc23c]

[Exo1i]

This pull request enhances the ConfirmCode password reset flow by introducing and testing a resend code timer. The timer prevents users from immediately requesting a new code, ensuring a 60-second delay between resend attempts. The changes include both updates to the component logic and comprehensive tests to verify timer behavior and edge cases.

Timer and resend logic improvements:

• Added a countdown timer (resendTimer) to the ConfirmCode component, which starts at 60 seconds on screen load and after a successful resend, preventing the resend button from being used until the timer expires. The timer is managed using a useEffect hook and cleared appropriately. [1] [2] [3] [4]
• Updated the resend button logic to be disabled while the timer is active or a resend is in progress, and to reset the timer only on successful resend attempts. [1] [2]

Test suite enhancements:

• Refactored and expanded tests for ConfirmCode to cover timer initialization, countdown behavior, button state transitions, and edge cases such as failed resend attempts not restarting the timer. [1] [2] [3] [4] [5] [6] [7] [8]
• Utilized Jest fake timers in tests to simulate timer countdown and validate UI updates and resend restrictions. [1] [2]

These changes ensure a more robust and user-friendly password reset experience by enforcing resend limits and providing clear feedback to the user.
