fix(i18n): add no_xlvask_usage_log_metadata to all 4 active locales

The first PR #313 introduced only the da translation for the
'no_xlvask_usage_log_metadata' preview key. The
i18n-v2-integrity.spec.ts test 'da v2 key set should match en v2'
failed because the en (and de, no, sv) locales were missing the
new key, leaving their generated v2 files out of sync.

This commit adds the key to all 4 active locales:
  - en: 'No metadata for XL Vask registration.'
  - de: 'Keine Metadaten für XL Vask-Registrierung.'
  - no: 'Ingen metadata for XL Vask-registrering.'
  - sv: 'Ingen metadata för XL Vask-registrering.'

Each locale delegates the registration label to the existing
xlvask_usage_log key (or glossary equivalent). Sources are now
consistent across da, de, en, no, sv.

Resolves the full master CI green-status attempt.
