feat(sprint-5): Phase 6 — Staff management UI (list, invite, permissions, revoke)
- /settings/staff: staff account table with role badges + permission chips
- Invite sheet: email + role template + 8 granular permission checkboxes
- Edit permissions dialog with optimistic update
- Revoke access with AlertDialog confirmation
- React Query hooks wired (useStaffListQuery, mutations)
- Full i18n (de/en), mock fallback, loading skeletons
- Sidebar nav updated: Personal → /settings/staff with UserCog icon
- Added @radix-ui/react-checkbox + Checkbox UI component
