fix: add dialog class to authcoreadmin modal overlay for E2E tests

AuthCoreAdmin's Tailwind CSS refactor removed the `.dialog` class from
the modal overlay. The E2E test selects `.dialog h3` and `.dialog button`,
so the class needs to be present. Fix applied both upstream (AuthCoreAdmin)
and locally (COPY . . overwrites cloned files in Docker build).
