UI Data-testid

Overview

Add predictable data-testid attributes to UI code as part of implementation, not as a later patch. Keep selectors stable across i18n text changes and visual refactors. Follow project testing rules in .cursor/rules:

• preserve existing data-testid during refactor/migration
• use data-testid-first query strategy in project tests

Workflow

1. Determine the scope prefix from feature/module context (for example: user-menus, organization-switch, settings-profile).
2. Add data-testid to the component root container.
3. Add data-testid to all primary interactive nodes:
   • button/link triggers
   • input/select/checkbox/radio controls
   • tabs/menu items/submenu triggers
   • modal/drawer open and confirm actions
