Save survey progress locally to prevent losing it

[zaynOm]

This pull request introduces functionality to save and load survey progress, ensuring users can resume where they left off.

It will Close #130

Changes Include:

1. Save Progress:

• Form data, sectionId, and questionId are saved to local storage after each step.
• Utilized helper functions to handle JSON serialization and deserialization for consistency.

2. Load Progress:

• Default form values are pre-filled using data retrieved from local storage.
• Handled cases where no saved data exists (fallback to default state).

Why This is Needed:

• Improves user experience by allowing users to resume incomplete surveys.
• Prevents data loss when users accidentally close the browser or navigate away.

Thank you @zaynOm for woking on this. i still didnt have the chance to review it but here is few remarks so far:

• Today is the last day of the survey, so it will probably be ready for next year's edition.
• As the form survey form is very critical, I recommend writing tests for the new functionality. , check here

Sure making changes while the survey's on isn't a good idea. I'll work on refactoring the code and writing some tests to make sure it doesn't break anything
