- legend uses m.admin_new_invite_groups() instead of hardcoded "Gruppen"
so screen readers announce the correct string in en/es locales
- label gets min-h-[44px] for WCAG 2.2 touch target compliance
- add test asserting fieldset accessible name comes from i18n key
- add test documenting empty-groups-no-error renders no checkboxes/banner

bind:group requires a writable $state variable; $derived is read-only
in Svelte 5, so every click was silently reset to unchecked, making
the group picker non-functional.
Also wraps checkboxes in <fieldset>/<legend> for WCAG 1.3.1 compliance.
