Form Architecture with BLoC

• Manage form state in a dedicated FormBloc (not in widget setState)
• Each form field maps to a property in the BLoC state
• Validate on field change (real-time) or on submit (batch) depending on UX requirements
• Emit FormSubmitting, FormSuccess, FormError states for submission flow

Form Events

• FieldChanged(field, value): update a single field in state
• FormSubmitted: trigger validation and submission
• FormReset: clear all fields and errors
