Extend toast notifications to all forms (bills and locations)

- Update billActions to redirect with toast messages
  - billSaved: when bill is created or updated
  - billDeleted: when bill is deleted
- Update locationActions to redirect with toast messages
  - locationSaved: when location is created or updated
  - locationDeleted: when location is deleted
- Enhance MonthLocationList to check for all toast parameters
  - Consolidated success message handling for all operations
  - Clean up all URL parameters after showing toast
- Add translations for all success messages (EN and HR)
  - Bill saved/deleted messages
  - Location saved/deleted messages

User experience: All forms now redirect to home with toast
notifications, providing consistent feedback across the app.
