Add and organize comprehensive Swedish translations (sv.json)

- Added extensive Swedish translations for dashboards, reports, bookings, POS components, settings, and common actions.
- Reorganized and expanded i18n keys for greater maintainability and consistency across multilingual support.
- Aligned sv.json with existing `en.json` and `da.json` structures to ensure seamless integration.
