+feat: dynamic input field sizing based on field type
+
+Input fields now adjust their width according to their specific function. Smaller fields like postcode inputs are resized, while larger fields like name inputs are expanded. Adjusted the `var(--utrecht-textbox-autocomplete-ui-size)` to `0px` for better alignment, though this may impact other UI components relying on the original `44px` size.
