suggestions in the `CreateEnvelopeWizardPopup` component.

with loading and state management logic. Updated the
`ReceiverService` to fetch suggestions from the backend API.

and improved localization support. Refactored state
management to handle loading, resetting, and applying
suggestions. Minor cleanup and adjustments to ensure proper
state transitions.
