Adapt to IPL strict typing in forms and i18n helpers (#617)

Use `ipl\Stdlib\Events` in form subclasses to satisfy IPL’s strict typing,
which is not met by using `EventEmitterTrait` directly.

Replace `gipfl\Translation\TranslationHelper` with `ipl\I18n\Translation` for
i18n support in UI classes. The module already uses IPL broadly for other
concerns, so this removes a redundant dependency and aligns with IPL’s
strict‑typing requirements.
