fix(falukant): improve product pricing logic and update localization for office notifications

- Refactored the product pricing logic in `falukantService.js` to ensure accurate regional pricing calculations based on client values and server data.
- Added new notification translations for "office filled" in multiple languages (Cebuano, German, English, Spanish, French) to enhance user experience and clarity in notifications.
