feat(ux): company context in settings, Kundfakturor rename, compact verifikat view (#1071)

* feat(ux): company context in settings, Kundfakturor rename, compact verifikat view

Support feedback (2026-07-19): active company invisible in settings,
menu said Fakturor next to Leverantorsfakturor, no compact verifikat view.

- ActiveCompanyBadge chip in the settings modal header and the full-page
  settings header; the modal covers the sidebar CompanySwitcher
- nav + page title Fakturor -> Kundfakturor (sv), Invoices -> Customer
  invoices (en); command palette gets a Kundfakturor page entry
- verifikat list density toggle (comfortable/compact), persisted per
  company like the existing sort/page-size choices
