i18n(events): RSVP page in it/fr/es + extract e2e helper

- strings.ts: add Italian, French, Spanish dictionaries (≈25 keys
  each) and widen Lang to the full DE/EN/IT/FR/ES set.
- +page.server.ts: pickLang now matches any of the five supported
  locales from Accept-Language; SSR error messages localised the
  same way.
- e2e/helpers.ts: extract the dismissWelcomeModal helper out of
  events.spec.ts so future module specs can reuse it without
  duplicating the locale-agnostic dialog locator.
