feat(modules): unify Vorsorge, Illness and Labs with the medication pattern

- add a wrench beside each module's add button linking to the module's own
  settings page; rename every add button to a plain "hinzufügen"
- give each module a settings page: view (cards/list) + manual reorder; Labs
  also gets a sort-order choice (by last reading) and biomarker CRUD/reorder
- collapse the Illness "abgeschlossen" list by default
- rebuild the Vorsorge card on the medication card's building blocks: a green
  "Jetzt messen" action, the interval as a chip beside the name, and an
  in-interval progress signal; drop the kebab "anpassen" and stray actions
- persist per-module view/order/sort client-side; add reverse-coverage-clean
  strings across all six locales
