feat: Add invalid ident notification for company register status checks

- Add notification system for invalid company identifications
- Update force delete notifications to handle invalid company cases
- Add translations for invalid ident messages (ET/EN)
- Add test coverage for invalid ident scenarios
- Remove debug logging from force delete process
- Clean up unused CSV templates

This change improves handling of invalid company identifications in the
Estonian business registry by providing proper notifications to registrars
and ensuring appropriate status updates.
