Subject: [PATCH] Add filter for recent receiver suggestions

Introduced a filter input box in `CreateEnvelopeWizardPopup.razor` to allow users to search recent receiver suggestions dynamically. Added `_receiverSuggestionFilterText` property and `OnReceiverSuggestionFilterChanged` method to handle filtering logic.

Refactored `ReceiverSuggestionFilterHandler` to simplify its API. Updated the `Filter` method to accept a single query string and removed redundant overloads. Improved filtering logic to match `FullName` or `EmailAddress` using case-sensitive comparison.

These changes enhance usability by enabling quick filtering of receiver suggestions.
