feat: Updated forms validations to use mode: onTouched across all components

[grandmaester]

Summary

Inconsistencies in form validation across UI components

What

1. Majority of forms (7 out of 15) use mode: ‘onSubmit’ to trigger validation, which delays feedback until form submission and the errors only appear after the users submits the form.
2. The users are forced to backtrack and fix the errors in fields they’ve already mentally ‘checked off’. This is a poor user experience.
3. This PR implements consistent validation across all forms using onTouched which standardize all forms to use onTouched mode for context aware, progressive validation and better UX.

Why

Current state: No consistent validation pattern across components as listed below

1. 7 forms use onSubmit ❌
2. 1 form uses onBlur 🆗
3. 1 form uses onTouched ✅
4. 4 form uses onChange ❌
5. 1 form has no explicit validation mode (defaults to onSubmit) ❌
