feat(manacore/web): localize app names with i18n (5 languages)

Add `apps` locale namespace (de/en/fr/it/es) with localized display
names for all 29 app modules. Workbench card titles, app picker, and
overlay headers now resolve names via $_('apps.{id}') with fallback
to AppDescriptor.name.

Key renames (de): Todo→Aufgaben, Habits→Routinen, Notes→Notizen,
Finance→Finanzen, Places→Orte, Mukke→Musik, Context→Dokumente,
Times→Zeiten, Cards→Karten, Picture→Bilder, Photos→Fotos,
Storage→Ablage, Questions→Recherche, CityCorners→Stadtführer,
Calc→Rechner.
