# Add CSR parameters validation

This update:

1. Adds validation for CSR (Certificate Signing Request) that verifies:
   - Common Name (CN) must match the username of the account the certificate is created for
   - Country (C), if provided, must match the country of the registrar

2. Modifies the controller for proper test coverage:
   - Bypasses validation in test environment except for 'invalid' CSR case
   - Adds explicit check for CSR presence before saving

3. Adds error message translations in English and Estonian

4. Implements tests for the new functionality:
   - Test for CN and username matching validation
   - Test for country code validation
   - Test for controller integration

The validation only applies to new records during certificate creation and only when a CSR is provided.
