bug: App Stops working when change passcode on iPhone

[AdityaSingh-02]

Describe the Bug

When you try to change app passcode on an iphone the app hangs and stops working, I think this is because of the 2 modals opening back to back the first one for validating the user and second one for changing passcode

Steps to Reproduce

1. Go to settings
2. opens Security and privacy
3. Set a passcode if you don't have one
4. Try to change it

I have been struggling with this issue all day, submitted a PR #6547 that provides a workaround fix.

Hi! I've submitted PR #6789 to address this issue since the existing PR seems to be facing some check failures.

Summary:

• Adds 300ms delay between modals to fix iOS hang
• Includes error handling for authentication cancellation
• Unit tests added and all checks passing ✅

Hope this helps move the fix forward! Open to feedback or collaboration.
