16.3 Hotfix: remove status entry when removing item (#20316)

* Add removeStatus method to repository manager

Introduces a removeStatus method to UmbRepositoryItemsManager, allowing removal of a status by its unique identifier.

* Remove item status on picker input removal

Calls removeStatus on the item manager when an item is removed from the picker input selection to ensure its status is updated accordingly.
