fix: align unsaved changes badge in Edit Feature modal tabs

The create-feature modal was refactored from .js to .tsx on main,
so the original fix was lost during rebase. Apply the same fix:
remove Row wrappers and redundant padding classes from tab labels,
letting .btn-tab__label handle alignment.
