Progress / steps done

1. Installed react-hook-forms and resolver for zod
2. replaced react states with zod schema

May need to be changed. I looked at the mongoose schema that is used for server side validation

3. Registered the inputs using rhf thus removing value and onchange
4. updated the Textarea component to have forwardRef which is needed by rhf.
5. Some inputs like toggle and icon search needed to be wrapped with Controller from rhf.
6. Each input now has a error message if needed (style and test probably need some changes as well)

7. userMilestone component needed states thus used watch from rhf to watch for changes thus live updating

@eddiejaoude let me know what you think when you're available!

[eddiejaoude]

Is there a way not to use position [0]? Because I can see this creating bugs

[ChinmayMhatre]

Don't get what you mean here

[eddiejaoude]

I mean using [0] seems strange to me? why 0, for example it causes confusion, why not 1 or 2

Looks good (I didn't test it yet though)
