i18n: settle measurement, practitioner, and visit-toast wording

- the single- and bulk-delete flows on the measurement list both say
  Messwert now, instead of switching to Messungen for the bulk case
- the practitioner field on the visit and vaccination forms reads
  Praxis oder Arzt on both, dropping the slash form and the lone feminine
  variant so it matches the practitioner list heading
- the visit saved/updated toasts lose their trailing period to match the
  vaccination toasts they ship beside
