Refactor interaction handling with utility for translations

Introduced `TermHelper.Translate` to centralize string mappings for `InteractionType`, reducing duplication across components. Updated related code to leverage this utility and streamline interaction row implementation by removing the `Caption` parameter. Minor UI adjustments were also made to align button positioning and styling.
